I must say I am impressed, Flock's tight integration with web 2.0 services like Digg, Flickr, Picasa, Blogger etc is amazing.
The default theme is a nice looking blue one. The first thing you are bound to notice is the large star button next to the address bar. The function of this button is to bookmark pages. The default homepage is ‘My World’ which hosts all your feeds from blogs and favorite websites. All the menus and options are just as in Firefox and Firefox users would be completely at home with it Flock.
Another big addition is the sidebar from which you can access your friends feed from Facebook. It also has many tricks up its sleeve when it comes to Facebook. There are options available to upload photos directly to online sites like Flickr and Photobucket. You can also view the feeds from streaming media like Youtube . The address bar has an envelop icon next to it, you can send the address of the website you are currently on by email. Flock also has an Blog Writer, the process of setting up the blog writer is extremely simple. You merely have to sign in to your blog with Flock to set it up. As simple as that! Highlight any text on a Web page and drag it to the blogging panel (which pops up when you click a blogging toolbar button), and your blog entry becomes instantly formatted with the highlighted text featured as a quote, nicely formatted in blockquote. The page link is bundled into the entry as well when you drag text. All of this displays in flawless WYSIWYG, and the whole presentation is pretty as a morning flower. Since its based on Firefox Flock can support mast but not all extensions used in Firefox.
The current version 2.02 of Flock corresponds to Firefox 3. Unfortunately the Flock devs don't provide a single .deb file to work with, rather they give you a tar ball to compile from. Even Synaptic doesn't have Flock in its repositories. However GetDeb guys have compile a .deb package for all of us. It is 14 MB in size and works perfectly in Ubuntu. Their photo uploader is damn sexy! I liked Flock so much that I have made it my default browser.
You can download Flock here.
Save it to some location and then install it by double clicking on the .deb file.
