What's the best platform for creating a CrunchBase like system? (has to be open source). Thanks!

              Your question is a bit vague, and there is never "one" answer to a question "which is the best for ..." ; still :
You are looking for a piece of software that allows, at least from what I can see on the site :
- users to register / login
 - edition of content
 - keeping of revisions history
 - tagging / categorization of pages
 - rss (both aggregating rss and generating rss)
 - comments on articles
 - couple of lists like "recently added", "recently modified"
 - some kind of search
 
That's the kind of stuff almost any CMS will do out of the box, I suppose...
If you are looking for something OpenSource, the next question is "which language / technology / platform"...
If you are going for somemthing Apache+PHP+MySQL based, Drupal is quite good piece of software, and you can do lots of things with not much coding, provided you use the right modules... and, as far as I can tell, it does what I listed before.
Of course, knowing a bit more about what you need / want might help us help you more ;-)

              Thanks for your reply. Druapl would be perfect for this, alas: I'm looking for cheaper development.Would you recommended ELGG for such a project? The main idea is indexing People/Comapnies/Organizations and display their connections and individual data.

                I don't know about ELGG, sorry ; never used it at all. Still, whichever tool you choose, you'll probably have to expect spending/investing some time in development (if it's not coding for the backend, you'll still have to spend some time customizing the presentation of the site, I suppose) : you don't create a website out of thin air ;-)
