I joined TechCrunch to work on CrunchBase back in October soon after the AOL acquisition and became the only non-editorial/sales person in here. My energies were split across a multitude of things and I found little time to devote to CB.
Over the past month however, we have hired two more devs, one to work on the blog network side of things and another who will be working on CrunchBase full-time along with me.
The frequency of commits has already started to show and we will be pushing out a number of improvements and features over the next few weeks. Top of the list is scalability and performance improvement since speed has been a bottleneck. There are other neat things such as trends/charts and more data widgets that we'd like to deploy. We are also working on cleaning up data integrity.
In short, I think you will see noticeable progress on CrunchBase within a few weeks.
