If you're interested, I'd be willing to give you a clone of the <a href="http://Newsley.com" rel="nofollow">http://Newsley.com</a> codebase.  It's a bit bare bones right now, and since I'm the sole developer, I haven't worked on the documentation much.   But, it's Python/Django, which might be a little more familiar to you if you're a Ruby/Rails guy.  I've thought about open sourcing the code, but some parts are a little ugly right now, so I haven't done it.  But if you're interested,  ping me and we can talk.<p>Another thought is Slinkset:  <a href="http://slinkset.com/" rel="nofollow">http://slinkset.com/</a>  It looks like they still have some active sites, and it looks like they've added features since I last looked a few months back.  Anyone know if they're still up?
