From the “one less Mike at Mozilla” files:
Mozilla VP of Engineering Mike “Schrep” Schroepfer is leaving Mozilla and headed to Facebook – to serve as Director of Engineering. Mozilla seems to like guys named Mike in key roles – there is Schrep, Mike Beltzner, Mike Shaver and Mike Connor.
There is no shortage of smart guys (named Mike or otherwise) at Mozilla so I personally don’t think that Schrep’s departure will have any significant impact on Mozilla operations. Mozilla Firefox 3 is already out the door and Firefox 3.5 isn’t coming till the end of the year.
On the other side, Facebook could sure use a guy of Schrep’s expertise on a number of levels. Schrep knows how to make development decisions and work with a community of developers (internal and external). So good luck to you Schrep and good luck to whoever replaces you officially at Mozilla.
