Just in case you haven't noticed, may I direct your attention to the top left of this blog, where there is a handy Search feature. If there's something you're looking for that doesn't have it's own category, try that out.
So, for example, if you wanted to find out if I've ever watched Have I Got News For You, just type it into the Search box and click Search Blog. The same process applies to any other TV show, film, book, author, graphic novel, band, solo artist, album, game, magazine... you get the idea.
This service used to be absolutely perfect, but at some point Blogger have completely mucked it up. Please be aware, therefore, that you're not necessarily seeing all relevant posts when you search for something.
