Annoyed/bored by some posts on Planet PHP? Then look no further than Sean's little Greasemonkey script. It let's you selectively disable the view of some blogs (if you're using Firefox and have Greasemonkey installed). Cool, saves me from writing something like that on the server side (but we had no plans actually doing that anyway).
Speaking of Firefox/Mozilla, 48% of all hits on Planet PHP in May are from those browsers. OTOH, approx. 50% are also on the RSS feeds, looks like a lot of people are using Thunderbird, Firefox LiveBookmarks or Sage for reading these feeds.
