How is Twitter going to make money to justify its high share price

Twitter went public the other day with is price gaining just over 72% on the first day, the second it dropped about 7%, but is still 50 times the value of its sales. That means that Twitter has to have huge growth and increase in sales to justify this current share price, or what will most likely happen in the sorter term is the share price will fall, leaving some investors out of pocket.

Twitter should look at how it can increase turnover and usage, to justify the share value. A lot of people I know have tried twitter and have not got on with it and don't understand it, I can see there point of view and I only use twitter to tweet articles that I like. Maybe they need to promote twitter and make people realise it is not just for following people you know and minor celebs, but could be for following music bands or companies that give useful information. On that point I do find the problem with twitter is the amount of rubbish tweets that appear, maybe there should be a way to filter out tweets and only receive tweets other users have found useful by a rating method.

It will be interesting to see what happens over the next few years with how twitter changes to make money and whether people will keep using it.
