I just got a crap HAT now too. Eactly 5 minutes ago I got a HAT, typed in some random crap into the box, then after that I was told "Im sorry; I have nothing for you. Have a nice day!"
I have an older computer running an old AMD single-core processor.. I use firefox and flashblock (So that there are no lag problems) and I can open 100 tabs at a time, with minimal trouble...
