Have you ever felt so bored with life that you have no Idea what to do? Do you have that extra pent up creative energy that you could use in putting up a blog but think that would be too much of an hassle? or do you just want to increase you knowledge and wikipedia is just not rewarding enough?
Well then look no further than Yahoos community driven portal Yahoo! answers. Being functional for more than 2 whole years now it has finally began to take shape as a genuine forum for increasing knowledge or just ask and answer silly questions. The format is pretty nice and quite unique. the main page has all the questions that people post and expect an answer for and the whole site is divided and sub divided into categories and there are enough categories to narrow your search down and limit the number of question you might like to answer hence decluttering the screen.
BONUS: If you have a genuine question to ask or a doubt to clear you can do it with a high degree of accuracy.
