Twitter's stock went down even though revenue went up. I won't bet on Twitter in the long run. I don't see them as an innovative company. On the other hand, FB constantly acquires new start ups and is more than just a social networking site now. They will go up and I think you probably could have kept it little longer.
Overall the market will 'correct' itself after bullish 2013. So don't buy anything yet as price will go down further. Then it will be a good entry point. Not too sure about selling. Last night idumb told me about green mountain coffee and today it gained around 24%.
disclaimer: i am a novice market follower. so don't hold me responsible for your loss but if you gain then i charge 0.20% consulting fee
