Lot of people share very insightful, thoughtful and inspirational tweets. Unless we are on Twitter for 24x7 it's impossible to follow such great tweets in real time. The search.twitter.com is good for people who can afford real time monitoring of tweets.

But for the rest of us, it's good to check good tweets voted by other users just few times in a day. That's the purpose of Tweeght - to learn from these insightful tweets. Hope it is clear now.
