Since Black Duck bought the site back in 2010 there haven’t been any obvious changes.
Until now that is:
Dear Ohloh user,
Since 2010, we have supported the Ohloh community, now consisting of over 250,000 users, with a stream of new features and functions – all to remain freely available. The name change to Black Duck Open Hub reflects an increasing commitment on our part to the developer community, as well as anyone who wants to learn about the world of open source.
So, goodbye Ohloh, hello Black Duck Open Hub!
I have to admit it doesn’t exactly roll off the tongue that easily, and I’m not looking forward to correcting all the mentions of it in various OSS Watch publications either, but hey, things move on!
