The second version of Buzzsaws is much like the first, with a few template adjustments and less aggregation. The neatest feature of Buzzsaws 2.0 is a PHP header generation script that creates a dynamic image of the post and/or category title using the Adam Warren TTF font. As of June 2009, it is still pretty bare.
Buzzsaws (version 1.0) is a powered by WordPress. It uses the LJXP module, a very slick component, to back posts up to a LiveJournal account. The Flickr and Ning feeds use a modified version of cache to pull new copies of the RSS every few minutes.
