I think the aMSN Project is great. I love to use this program on my Ubuntu system. It's simple to use and has an incredible plugin system. Not to mention it's open source, which makes it 10x better for developers, and people who want to learn how an Messenger application works.
Even though the project is kinda large now, I personally would like to see it become bigger and better. Meaning, more addons, different open source versions developed by different developers. Making it even more fun to use.
But how do we do this you ask?
Facebook

I'll post the link at the bottom of this post. But basically it's a way to get free advertising space ($270 worth) on facebook. I think if enough people gathered together, we could get a lot of advertising going on the facebook website.
And in turn, getting a lot of people visiting, and possibly joining the development of aMSN.
Good idea? Possibly.
