Not including this website! Any topic. Mine: 1) My Yahoo. I know they are in league with the Devil, but I have gotten alot of value out of being a member of this free service for (over) seven years. It's a convenient homepage, and quickly provides information on news, weather. sports and stuff. I think alot of people take it for granted. I would probably include the Yahoo search engine; but since it's integrated into My Yahoo, I won't. 2) Photobucket. Also free, easy, and it works great. 3) The Internet Movie DataBase (IMDb). Handy for looking up trivia. 4) Wikipedia. People talk about how it can't be trusted... but for the most part, the information is correct, thorough, and handy. 5) Amazon. It's like crack to me. I love books and DVDs, and the idea that I can shop for them online and they will show up in my mailbox is hard to resist. I have also used Amazon as a sort of research tool, not unlike IMDb. It's pretty rare that I turn on my computer and I don't look at all five of these. Most of these are things I use as "tools" versus left-brain stuff. So, I'll include an honorable mention that I enjoy.... MisterSF.com I searched, and didn't see a thread on this topic elsewhere. My apologies if I missed it.
