In recent nightlife history, people used to be able to tell if a weekly party was good based on whether or not a nightlife photographer stopped by to capture the mayhem. This was good news for photogs like Mark the Cobrasnake, Ambrel, Nicky Digital and Jeremy Kost. But now, Cobrasnake and Jeremy Kost reveal more about social circles and house parties than a nightlife scene, Nicky Digital has been settling into the same venues, but has upped his blogging and video content to include more music and servicey things and Nikola Tamindzic's Ambrel is defunct. It's much more of an egalitarian society these days: Between tweets and Facebook invites, everyone is a promoter, and you can usually make out the social lines drawn in the sand by doing a search. Today, we can tell if subMercer is a party from our friend's own photo album and if Su Casa on Wednesdays is any good by reading twitter. So what are the kids saying? A collection of the best parties, old and new, with some help from Facebook and Twitter.

SUNDAY

Lowdown: Sundays have been a solid party night, even through the bluster of the winter season. Hot Now: ● GoldBar (Nolita) - Frequented by the Ronson clan and celebfolk who go unrecognized by a collection of spendy bankers. A favorite amongst models, Danny Masterson, and DJ Jesse Marco. ● Sway (Sway) - Moroccan themed bar has become the Pants on the Ground song. Sort of creepy, but a guilty pleasure and viral. ● Greenhouse (Soho) - The Van Dam party isn't Dem or Rep. They're for the green. ● White Slab Palace (Lower East Side) - Another odd place to stumble into late night. Hit or miss and always a "Where did all of these people come from?" moment.

MONDAY

Lowdown: Monday night means the beginning of your drinking week. Hot Now: ● Stanton Social (Lower East Side) - Yes, still a great place to have a fun bite/Monday night drinks. ● Butter (Noho) - Not only is this a truly great place to get sloshed on Mondays, I am now excited to admit it. There's a cool, younger crowd that's mixing in on Mondays and adding a bit of an edge to the festivities. Worth a Look: ● Black & White (Greenwich Village) - Restaurant becomes cramped, sexy, and very cozy after ten. ● Warren 77(Tribeca) - Just right for football fans with a bit more flair. ● Johnny Utah's (Midtown West) Football season is over, but it's still industry night here.

TUESDAY

Lowdown: The hipsters take infiltrate the clubs, Nur Kahn maintains at Rose Bar. Hot Now: ● Rose Bar (Gramercy) - This really has a lot to do with Nur Khan, and now the music enthusiast is upping his game with Nur Kahn's Rose Bar Sessions, featuring a band every Tuesday night. But they are secret shows. So shh. ● Avenue (Chelsea) - People were astounded to find this place under our Tuesday heading: "Duh, the hot nights are Monday and Wednesday, obvi." Those people are right, but those people have never known the true Bea. And really, Avenue is good every night -- right? ● 1Oak (Chelsea) - Right around the corner, the one-of-a-kind kids get the spillage of displaced hipster kids, who can't decide between one gilded lounge or the other. Again, people agreed to disagree -- and with a name like "Tight Jean Tuesday," we know Jay-Z's knots don't fit. ●Superdive(East Village) - Champagne Tuesdays. Champagne in a dive bar. Say no more. ● SL (Meatpacking District) - Might be able to add another notch on its belt; Tuesdays are hot at SL. ● Greenhouse (Soho) - Green followers love Tuesdays too.

WEDNESDAY

Lowdown: Hump day isn't just for humping. Hot Now: ● Le Cubain (Lower East Side) - Great spot for pre-drinks and cheap eat with babes with bangs in boots and vintage fur coats. Maybe even make it downstairs for a Chloe revival -- bottle models pack it in pre-1Oak and Boom Boom Room. ● 1Oak (Chelsea) - This is still 1Oak's undisputed hot night. ● Greenhouse (Soho) - This one is in the basement, kids. Well, it's in the whole of Greenhouse, but it's better down below. ● Avenue (Chelsea) - Again, Avenue. But this is a raging night for the kids on the Ave. ● SL (Meatpacking District) - Tonight is the night for this Aalex Julian-guarded door. ● subMercer(Soho) - You may have forgotten about this celeb-laden underground, but she's back, along with her FAM (Friends and Music). Featuring Gabby, Richard and Tariq.

Meet The FAM - 8pm Wednesdays @ subMercer from Tariq Abdus-Sabur on Vimeo.

THURSDAY

Lowdown: This is Manhattanites' Friday night, which explains why Butter is moved their dancey Friday party -- Whipped -- to Thursdays. Dancing, dinner, glitz, and even some glam, without the B&T jam. Hot Now: ● CV (Lower East Side) - Something has finally been done with the over-saturated spot formerly known as 105 Rivington. Hopefully Amanda Leigh will continue with the feel good vibes and attract a good, loyal crowd. ● BEast(Chinatown) - Main Man, Ryan McGinley's night of debauchery, is still in swing. Expect a Misshape or two, Sophia Lamar, and a band of insiders. ● Coffee Shop (Union Square) - One of the true day clubs, chocked full of promoters networking via text message; the basement named USL will be making random appearances throughout the week. Worth a Look: Avenue, Boom Boom Room and 1Oak are still a great standby for good times, while the down belows like Macao's basement opium den, is also great. Coming Up: ● Butter (Noho) - Thursday-night party Whipped is so fresh, most can't believe it's Butter. Resident hipster DJs Matt & Maia draw out big name fashion folks like Alexander Wang and the Ronsons.

FRIDAY

Lowdown: It used to be a day of rest for jaded New Yorkers, but since we've stopped bleeding moola, Friday's a great day to cut loose. Hot Now: ● Boom Boom Room (Meatpacking District) - You probably won't make it in like the rest of the plebeians (us included), but if you could, this would be the night to go. ● The Standard Grill (Meatpacking District) - What's that, didn't make it in to Boom? Luckily, the Grill is jumping with everyone else who tried their luck and are now eating duck (or crow); even the most beautiful, classy folks gather here, so it's a hotspot nonetheless. Worth a Look: ● Home Sweet Home (Lower East Side) - Jonathan Toubin brings the fairly popular New York Night Train to this little living room on Friday nights. ● Santos' Party House (Chinatown) - A Tribe Called Quest's Q-Tip. Upstairs. Funk.

SATURDAY

Lowdown: Whether you are above or below 14th Street, you should probably be planning on going out somewhere near to or below 14th Street. Hot Now: ● Boom Boom Room (Meatpacking District) - Again, try your luck. ● Lit Lounge (East Village) - Saturday night is grimy and fun! ● Bowery Hotel (East Village) - Simonez throws ragers here, spanning Thursday, Friday, and Saturday night. Worth a Look: Bagatelle (Meatpacking District) - Bagatelle's scene gets an early start with their Rock and Roll Brunch.
