Cornerstone vs Versions
I dont know how long Cornerstone has been around (actually, according to their blog it looks like the first version came out around May 2008), but i only learned about them last week (an ad in Tweetie), and immediately downloaded it. I spend all day every day working with code stored in different Subversion repositories. Up until now, I have been using Versions as my Subversion app of choice, and its been great. There are a few annoying issues with Versions, and i’ve been surprised at how long they take between releases, but it was the first Subversion app for the Mac that was actually worth using.
