Project Place offers a range of services from webinars, a blog, to PM software. They offer quite a bit of services and is free for small projects - but also have enterprise opportunities.
I have been looking for an opportunity to use it for a small scale project and try it out. Implementing technology to a project team is always an interesting and challenging circumstance. You need folks to buy in and use the software. You can only test out a piece of collaboration software by yourself to a certain extent. But all software packages have good points and bad, some may be able to work out - sometimes you may need to test other solutions - but care needs to be taken as multiple changes in technology can be even more difficult to manage.
At any rate, I like the information this company provides, I think that helps adoption, and knowing if it is a good fit for your environment in the first place. Further, even without adoption there is a wealth of knowledge that is useful in terms of PM techniques that are worth exploring.
