For the past several weeks, we’ve been making improvements to CrunchBase to build a more engaging product for the people that drive it – which is to say, “everybody”. Since it was launched, Crunchbase has always been a freely editable repository of information about technology companies. Since February 2008, we’ve received over 100,000 edits from anonymous users in addition to the copious amounts of information that TechCrunch writers funnel to it on a regular basis.

We’re excited to announce that these contributions no longer have to remain unattributed. Starting today, anyone with a Facebook account can sign up for an account on CrunchBase by using Facebook Connect. Edits will still be moderated (after all, this is the Internet we’re talking about here), but users who prove themselves to be trustworthy will, with time, start to see additional privileges associated with their accounts.

All of these edits represent a treasure trove of information, so we’ve also been working on ways to better present the edits as they occur. Visitors to the CrunchBase homepage will now notice a list of recent milestones – a “stream,” if you will – that represents the most recent changes to the database. We’ve filtered out the more trivial edits in an effort to make this the kind of real-time information that even Paul Carr could love. These funding rounds, acquisitions, investments, IPOs, and other major milestones will now also appear on the individual pages that they relate to.

Ruby on Rails is well-known for being a powerful tool to help developers quickly turn ideas into working code. Rails Rumble harnesses that power and drives it to its only logical conclusion: a 48-hour programming competition pitting more than 200 teams of coders against one another for some pretty serious prizes. Each team of up to four people is provided with exactly the same thing: a virtual private server from Linode, a private repository on GitHub, and a really tight deadline. BYO caffeine.

The competition has ended and now that many of the contestants are awake again, it’s time for the public to kick the tires on these mini-applications and vote to decide who will take home the championship belt (and no, that’s not a figure of speech in this case. There really is a belt). The 22 finalists include something for everyone, whether you’re a developer working to nail down requirements, a boozehound trying to figure out what cocktails you can make with the leftovers from last night’s party, an old-school arcade nut looking to play multi-player Asteroid, or a hopeless romantic trying to employ Twitter to woo a crush.
