Techcrunch notes that the rumor mill is heating up on an imminent IPO from MySQL:
I am hearing chatter from hedge fund circles that the filing may be imminent. Last I checked, nothing has been filed with the SEC yet.
All quiet on the western front, but with growing market share (25% by Evans Data's estimates) and an increasing ability to monetize that usage MySQL may well be ready to put itself in the public eye. This would be a major coup for the company, obviously, but also for open source, generally. Frankly said, we need more monetary proof points that open source offers sustainable revenue models.
