First I went to the entire directory and browsed a little bit. I'm thinking about trying my hand at cooking, ok, stop laughing, so after looking at a couple of sites, I signed up with one called Foodari (kind of like my favotire site shelfari but only for recipes). You don't need to register if you only want to browse recipes, but if you want to store your own recipes and find friends that can share recipes then you need a profile. I decided to register just to check it out. What I didn't realize is that although you can view videos on how to make different things and get tons of recipes, the site is UK based so everything is in grams and a lot of the items used in the recipes are not normal to the things you'd find in US recipes.
Then I looked at the Top 20 list and was surprised as to how many of the applications I've actually used at one time or another especially now that I have an iphone. I have the Urbanspoon, Yelp, Twitter, Pandoa, Flickr, Zillow and Facebook apps on my phone.
Friends have sent me links to Bebo and LinkedIn so although I looked at them and have accounts, I don't really use them.
I tried using Flock as a browser at home for a while, but didn't take advantage of all of its uses and wasn't completely enjoying it so I went back to Internet Explorer.
I have a Pageflakes account and use that on occasion, but not very often. It's kind of like having your own Google page where you can customize what links are on it - flickr, games, calendars, facebook, etc. so everything is within the same interface without having to go to separate pages to use them. I learned about Pageflakes at the last LI Library Conference I went to I gave it a try. It's too bad I'm set in my own ways and that it takes forever to load.
I've shopped on Etsy before and really like it. They have such cool and unusual stuff which is right up my alley. Sometimes things can be a little expensive, but it's cute so who cares! :)
I also have apps on my phone for Foursquare and MyTown where you check into the places you visit to earn points and badges. You can post where you've been to Twitter and Facebook and can also add your friends from there as well. I'm still getting used to them so half the time I go someplace I forget to check in until I'm already on my way home.
There are so many cool apps out there that I'll probably keep looking. I hope you guys find one that you like as well.
