Whew! :D
Now some of these are really sub-categories, but I decided to include them here for completeness.
Kristie found that fashion blogs were the most searched for but they're only in second place in these results, beaten out by (somewhat bizarrely) maths blogs! I'm not sure what's going on here, maybe there's a school project to create maths blogs or something! Any ideas?
