Mark Otto and Jacob Thornton are known for developing Twitter Bootstrap. The two are leaving Twitter after working at the company for about 2.5 years, but they are not falling far from the Twitter tree. Otto and Thornton said that they will both continue to keep working on Twitter Bootstrap. Bootstrap has grown beyond them said Otto. Here is what they wrote on Hacker News:
The timing has nothing to do with a disagreement about Bootstrap (seriously, none what so ever), and more to do with us both wanting a change in our own lives for what we do day-to-day. Twitter, the company and product, are both amazing and Jacob and I have worked there for 2.5 years.
We?re stoked for our next things and we both want to keep working on Bootstrap no matter what. We have an obligation to the community and know it could go much further. (Oh, and yes, I screwed up the date on the post. My bad, yo.)
Bootstrap was created by me at Twitter as a means to make better looking internal tools. ? It started off as a simple HTML/CSS thing, then Jacob built plugins on top of it, and we open sourced it together.
We made it at Twitter, so when we wanted to open source it, we went to Twitter to ensure it was good to go. Thus, it was named Twitter Bootstrap (originally, ?Bootstrap, from Twitter? actually).
Now, it?s back to just ?Bootstrap?.
It was a few weeks ago when Otto and Thornton announced Twitter Bootstrap version 2.1 with simplified documentation and some fixes. Bootstrap will remain as a Twitter project on GitHub. Otto will be working at GitHub and Thornton will work at Obvious. Obvious is a startup incubator that Twitter has it’s origins from.
