Thinkfree is a web 2.0 tool. It can be used to put your documents on a account that allows you took access them anytime anywhere when you need them.

Kyolo

Kyolo is a web 2.0 tool that can be used for one thing. That one thing is adding text bubble to things.

I dont see this as a very useful tool due to its limited abilities.

logoease

Logoease is a web 2.0 tool. It can be used to make icons and logos. Other than that I dont see much use for this web tool.

Meglobe

Meglobe is a web 2.0 tool that is used for messaging. It can be used to email other people and can translate it to different languages. This can be a useful web tool if you are emailing people that speak a different language than you.

Babbel

Babbel is a tool to help you learn other languages. It can be a usefull tool but I think there are better ways to learn another language than a not widely known/recognized source.

foodblogsearch

http://www.foodblogsearch.com/
Food blog search is a web 2.0 tool I dont see much use for. Alls it is is you can post food, recipes, etc...

I dont see much use for most chefs I dont think would go look it up on the internet they would probably just look in a cook book or something.

Xurrency

http://xurrency.com/
Xcurrency is a web 2.0 tool that I dont see much use for. Only use I can see it for is worldwide trade and exchange of money which not many people do.

So in my final opinion it is not a very useful tool unless you are dealing with another country.
