I mostly use Google Chrome so I use Speed Dial 2 as my home page. It has a nice GUI and syncs all my dials with my other google chrome browsers which is nice seeing as I use it on both my windows and ubuntu partitions. The dials I have at the moment are PokéCommunity, deviantART, Twitter, Hotmail, Facebook, YouTube, PokéPasta and then Tumblr. I'd probably have Imgur on there too if I could find a dial image I liked.
When I use FireFox though I just use whatever is default for the browser so I think I have the ubuntu google search page on one and the firefox google search for another.
Oh and then I have PokéCommunity set as my Internet Explorer homepage.
