Thanks to Pao, I finally got my wallop invitation. For those who aren't aware of wallop, it is a 'Yet Another Social Networking Service' from the stable of Microsoft. Presently more of a research program than a commercial service, wallop is trying to add two new dimensions to the realm of social networking- music sharing and blogging.
I haven't yet played around with it a lot but it looks real neat. My first impression: stunning interface! It is very intuitive to use for most of the functions with a very appealing layout all done in flash. The network tree on the left has all your contacts arranged as nodes giving a clear picture of how you're connected with them.
Besides the option to upload pictures and share music with others, it also provides a favourites section to bookmark text entries and pictures. You can also make RSS feeds of your wallop blog and use them externally or publish it as html on the web with a public url. And the most wonderful part, it also comes studded with a RSS reader to import RSS syndicated sites. However, it doesn't seem to have anything like a 'Community concept' like the one in services like Orkut.
