A fresh infusion of investment cash pushed Twitter’s market value up to $3.7 billion on Wednesday with the number of people using the microblogging service climbing to 175 million.

More than 25 billion “tweets” were fired off during the past 12 months, with Twitter adding 100 million new accounts during that same time frame, the firm’s chief executive Dick Costolo said in an online post.

Venture capital firm Kleiner Perkins Caulfield Byers headed a new round of Twitter funding, which technology blog AllThingsDigital said tallied $200 million dollars.
