Twitter tops Wall Street revenue target, user growth slows

By Alexei Oreskovic SAN FRANCISCO (Reuters) - Twitter Inc beat Wall Street's revenue target in the fourth quarter but the pace of its user growth weakened, adding pressure on embattled Chief Executive Dick Costolo.

Twitter said it ended 2014 with 288 million monthly users, up 1.4 percent from Sept. 30. T
