(Newser) – Twitter’s latest private fundraising effort values the firm at up to $7 billion, an insider tells the Wall Street Journal. Just seven months ago, a round of fundraising that brought in $200 million valued the firm at $3.7 billion. Twitter is hoping its ad system, begun last year, will someday boast billions in revenue. This year, ad revenues are set to reach $150 million.
