I played around with Flock some more and I have a better feeling of the same. In my earlier blog, I had overlooked the fact that it is a beta version of the product and the minor issues can be pardoned.
Some cool features I like are automatically saving the bookmarks to del.icio.us, reading my blog as a feed etc.
Now I really like the idea behind the Flock browser. It tries to harness the power of Web and integrate many applications like blogs, flickr photos, del.icio.us etc. This concept is very powerful and is the part of the recent ideas like Web 2.0, Social Network etc. But in order to achieve the status of a social browser, Flock needs a lot more power. George talks about this in his blog. He talks about a social browser which provides good visualization of the wide-spread content on the web. He calls this application FolkMind and has started an Open Source project named Folkmind for the same. It is really interesting, especially the project's caption "Virtual brain of humanity" :-)
