Where are the original Facebookers these days? Well, Zuck is attempting to steer Facebook through the rocky shoals of a slipping stock price. Peter Thiel is unloading his stock and donating to Tea Partiers. Eduardo, presumably, is popping bottles with models in Singapore.

Meanwhile, as the Huffington Post reports, Sean Parker is defending his legacy on Twitter.

Back in late July, Sean Parker told the New York Times that, "Every good entrepreneur I know ends up in the wasteland of being a venture capitalist. It's really frustrating." Right, well, as Inc. writer John McDermott proceeded to point out, Mr. Parker hasn't spent the last few years setting the tech world on fire:

Since Parker is so quick to judge, we presume he'd include himself on that list of brave entrepreneurs [who continue to found new, successful companies]. But his track record is a bit spottier.

Yes, Mr. Parker has Napster and Plaxo to his credit. However:

Parker's entrepreneurial activity has leveled off a bit since then. He became the inaugural president at Facebook--yet although he is frequently cited as an integral part of the company's early success, it wasn't his endeavor.

Mr. McDermott also called Airtime's launch "more buzz than business."

Well, perhaps Mr. Parker was doing a little idle self-Googling yesterday, because he suddenly went on a Twitter tirade, rebutting Mr. McDermott's post:

@j_m_mcdermott a bit spottier? It's not about "founding" a company it's about being an entrepreneur. Let's look at the track record..

(Please note: This is best imagined with Justin Timberlake portraying Mr. Parker.)

@j_m_mcdermott There were only three legal founders of Facebook: me, Dustin Moskovitz, and Mark Zuckerberg.

— Sean Parker (@sparker) August 23, 2012

@j_m_mcdermott This was substantiated by every company legal document from inception.

— Sean Parker (@sparker) August 23, 2012

This puts last year's reported screaming match with Zuck in perspective, no?

At any rate, Mr. Parker added, he was making a larger point about something grander than mere business:

@j_m_mcdermott My point was not about "founding" a company, in some pedantic sense, but about risking everything and going for broke.

Mr. Parker seems to have confused the definition of entrepreneurship with that of poker. Despite the similarities, one is usually considered to involve starting a company.

FIT FIGHT. Fitocracy, the fitness game that uses points and milestones to keep us motivated and moving, is now available on iOS. Users can see what their friends are up to and add and log new exercises right from the palm of their hand. To accompany the mobile app launch, Fitocracy has revamped their website, making it easier to see friends' updates, browse achievements, check scores and see how many points away from the next milestone they are. Slimkicker, a similar app, also made its iOS debut on the same day.

THERE'S ANOTHER MAPP FOR THAT. This week, MyCityWay, a mobile app that combines reference app information with city data, won the “Best Travel App” award at this year's Appy Awards. The app can be used for anything from job searches to driving direction to ordering Chinese food.

DEEP IMPACT. The next installment of the NYU Series on Impact Investing will be on April 9 at Vanderbilt Hall in Room 210 at 6:30 p.m. on the NYU campus.  The panel discussion will focus on legal and policy issues and how they impact investments.  This and future installments will focus on "issues related to the measuring of impact, the key regulatory questions raised by impact investing, and the role that development finance institutions play in impact investing." More information is available here.

TO WHOM IT MAY CONCERN. Quotiply, a business app that connects companies and helps them collect, rate and assess offers from providers, just came out of beta last month. The app has profile, messaging and address book features built in and will even make suggestions to help members find good business partners. Quotiply is currently based out of Paris but CEO Paul Dupuy is currently in NYC with the team until the end of April. The company plans to move to NYC as soon as possible.

VIEWTUBE. Some pretty noticeable people including Hank and John Green, and Michael Aranda are using VYou, a video blogging platform, to answer questions and communicate with their fans. Annie Barrett of Entertainment Weekly uses the platform to do show reviews. Daily Candy has a channel where editors answer questions from the audience.

TECH SIDEKICK. Code for America needs a “Gotham Brigade Captain,” whose job will basically be to help bridge the gap between tech and government.  The job will involve high-visibility and a firm grasp of the complex relationship between government, the law and technology.
