Besides the fact that the performance is a bit slow (Jive is still working on it) the new VMware Technology Network looks great. If you are familiar with VMware Technology Network (VMTN), you will see all of the functions you have come to know, plus a number of new functions like personal blogs for all community members, collaborative wiki documents, wysiwyg editing of discussions and wiki documents, tagging of all content, improved search, and replying to threads via email. These features are meant to increase the benefits you get from participating in the community. You really should take the quick tour.
