That is kind of the opposite of innovating, no? The idea that the company is depending on prior innovation? Unless you are saying the updates contain innovation.
I don't think Twitter has had anything to do with Bootstrap for a significantly long time. fat and mdo left twitter 10 years ago.
Can't tell if this is snark, but gotta hand it to the Twitter Bootstrap project for making off-the-shelf CSS libraries acceptable.
Setting aside the timeframe.
Bootstrap is not a revenue generating function for them.
I admit I had the timeframe wrong, but whether it generates revenue was not part of the question.
Fair enough. I should have stipulated my point as "customer innovation".
It seems like Twitter is facing the same issue FB is. Behind the scenes innovation, but not customer facing.
