....do you find this site better than yahoo, why ...

While there are many similar questions posted on both I have found that many of the responses are more sympathetically and intelligently answered on Yedda.

Also, on Yedda, based on your profile, you are invited to answer questions that are related to your interests/experiences.  This is the coolest thing about Yedda.  People aren't just answering any questions, they have been invited.

one thing I like here is the simplicity in terms of replying to questions, just one click and that's it answer posted unlike in yahoo answer you have to load two pages such waste of time for me.
