Yahoo has entered the world of social networking websites with Yahoo! Mash. The site is currently in invite only mode so if you would like to check it out just drop me a line or post a comment. There is a great review of the new service here and it is worth checking out! it is very easy to use, changes are made on the fly, and the list of plugins are impressive. It is much easier to create a new page in Mash compared to the other sites out there you are familiar with.
