Fluther, Gmail, Youtube, Google, Wikipedia, sometimes Facebook, Bebo, Twitter etc. then I use Stumble a lot for the fun of it. Besides that I tend to just hang about doing…very little.
I will add some not already listed:
netflix, hulu (a tip o’ the hat to the collective for pointing me to this one…..), and a mulitude of others that are used weekly….but not daily as per the question.
Fluther, Askville although I haven’t been there much lately, Marapets to keep an eye on what my kids are doing there, although I enjoy it too, Shelfari, Fantastic Fiction, Amazon.
