These are just a few of the many links I consider the most critical, most entertaining, or just “most linkable” on the web. Feel free to criticize or suggest more. I don't generally include personal sites or the like here, but I'll be happy to give a shout-out in a dedicated post if I like the site. Personally, I visit only Gmail and Google Reader on a regular basis; most of the other sites are either for reference or are loaded as RSS feeds into Reader.
