Lifehacker Feed Cleaner 2.0
Gives the full-feed instead of summaries. Uses Lifehacker tag exclusions to filter at the source (e.g. retro-roundup, getting-things-done, gtd, etc). It has filters for things tags can't do, like keywords in titles (e.g. sponsors). Best of all, it has enough branching logic to do things like block all posts tagged Mac but not Windows. Clone it to customize to your preferences! (pipe formerly known as MyLifeHacked.) Last updated: 02/28/11 after their RSS changes following their latest redesign.
