It's a magical time in young Twitter's life. At the end of last week, CEO Dick Costollo called some reporters over to the company's headquarters for some big announcements. Twitter's hit the 100 million user mark, even more important are tweeting (85 percent of US Senators!) and their revenue, well, they'd figure that out. It felt kind of like a high school graduation ceremony. The end of this week brings another set of big announcements. Twitter veteran and chief scientist Abdur Chowdhry has left the company, and early investors Fred Wilson and Bijan Sabet are stepping down from Twitter's board. We'd compare it to the first day of college.
We all know that Twitter's growing up, and the motives behind the shake-up in the family are unclear. Chowdhry joined the company in 2008 when Twitter bought his company Summize and has been the paternal force in shaping key features like Search, Recommendations, and Trends. Wilson and Sabet are actually a bit more like the rich grandparents. The two seasoned venture capitalists helped Twitter onto its feet in the early days. In the company's own words, "Both saw what Twitter could become before most anyone else." Having just closed a massive round of $800 million in funding, Twitter has most definitely become something huge.
