I was able to install the latest Yahoo Messenger. I have been using it for a week now, and just this morning, I found out that whenever you give a link of a Youtube video to your friends through Yahoo Messenger, the video would actually be shown on the Messenger window. Check the screen shot below.

This is indeed a great upgrade, to have an ease on the users side, because they don’t need to open the video URL, but they could watch it instantly from the messenger window while chatting.

Is somehow the same as Blog Catalog. The idea, is to be able to have a widget on the sidebar,  to know who visited your site, without the visitors leaving any message.

This is also good for marketers, to know bloggers or blog that is about a specific topic. You could check the community and have huge list of bloggers within that said topic. There you could get a list of people you would like to get in touch with while promoting a site.
