Flock, who's gonna use it?

I've been playing with it for a little while, and there are some things that I really like about it:

- Bookmark Tagging - a really nice way to keep all your bookmarks organized, and much more flexible than using a folder-subfolder hierarchy.
- History Search - webpage contents are indexed while you browse and as you start typing a search term into the search box at the top-right corner, you get a list of all the sites that you visited that contained the term. Very nice.
- Feed aggregation is done well, although it won't be replacing my regular RSS reader.
- Integrated blogging - there's something called the Shelf, which is like a dropbox/scrapbook for web content (text, images etc.) that you want to use in your blog post. Drag stuff onto it, start composing post and drag stuff off as needed. Convenient. Supports Flickr too.

Favorites also auto-sync with del.icio.us. I don't use this personally, but I'm sure there are those who will love this.

Being a beta, there are obviously issues. It tends to get slow and laggy quite often, and I did notice a few bugs, including a memory leak. It's not ready for primetime yet, but it's definitely very promising. I'm going to keep my eye on this one. =)
