A number of different Web browsers are available for Linux with mildly differing features. The number one browser, of course, is Mozilla Firefox. Other Gecko engine-based browsers are Epiphany and Galeon. And then there is the KHTML-based browser, Konqueror.
Another addition to the available browser choices is Flock, which is also based on the Gecko engine. The difference between Flock and Firefox is that whereas Firefox tries to be a mainstream browser for all users, Flock's primary focus is on the "social Web" and its features reflect this.
Flock provides support for a number of social networking experiences. It's currently in beta, but already the feature-set is unique and promising. The first and probably strongest feature in Flock is the Flickr and PhotoBucket picture-sharing support. Flock makes it easy to upload pictures to your Flickr account by simply performing drag-and-drop operations or using the batch photo uploader. There is also support for updated picture notification; you can maintain a Friends list of others who use Flickr or PhotoBucket and be notified when their pictures have been updated.
Another feature is RSS aggregation. With Flock, you have a built-in RSS reader that can be used to preview, subscribe and receive updates on various RSS feeds from technical sites to news sites to a friend's blog.
Flock also takes on a new approach to searching. When you type a search term, Flock returns results from your bookmarks, your browsing history, and live results using the Yahoo search engine (Flock is partnered with Yahoo for a number of different social services). The unique thing here is that Flock contains a built-in search engine that indexes the content of every Web page visited. It also provides a listing of alternate search engines.
Finally, Flock has extensive support to ease the posting of blog entries, provided you are using a supported blogging system such as Blogger, Drupal or WordPress, among others.
Although Flock is still in beta, it shows a lot of promise, particularly if one of your uses of the Web is social. Most Linux distributions do not ship with Flock yet, but downloading and installing from the Web site is quite straightforward (no compiling required).
Talkback
I've been using Flock on Linux and Windows for some time now ... since 0.3 or some craziness. I can't ditch it. I tried going back to Firefox, tried going back to Konqueror (which was once my main browser), but I just can't. For me, having my del.icio.us links as my bookmarks/favourites is absolutely unbeatable. I haven't had to sync my bookmarks between multiple computers in AGES!!
The built-in blogging and photo features are great, but one other you missed is the snippets area. You can highlight, drag, and drop anything from any page to the snippets area and drag it back into forms/text areas/blogs/whatever. AMAZING for quoting articles with ease.
It'll take another fabulous browser to unseat Flock from my desktop. Just like the early Pheonix (->Firebird->Firefox) bounced Opera off my desktop. For now, Flock rules!!
