Slow, slow, quick, quick, slow

I finally figured out what was slowing my Mac down; a quick look at Activity Monitor (why did I not do this before?) revealed that a toolbar application called RSS Menu (it does exactly what it says on the tin) was using up a whopping 46% of CPU. A very handy application but it will no longer be gracing my screen. Use a free Newsreader such as Vienna instead if you need to read feeds; RSS Menu is not worth the hassle.
