I'm currently using the Yahoo YUI javascript library in a couple of my projects. However, I'm a little concerned about three things. First, they laid off 10% of their employees. Second, their stock price keeps falling: especially after ignoring the MS takeover earlier this year. Third, what if someone does buy them? The only reaso...
