LotusLIveThis hit the Twittersphere yesterday and was also blogged about by Stuart McIntyre on his LotusLive blog… the combined services of LotusLive have now attracted 18 million paying subscribers. Since we started the year with zero paying subscribers that’s pretty good growth. The story is then picked up by ZDNet who theorise that the annual revenue from those subscribers could be $648 million, thus justifying IBM’s acquisitions and development efforts… and indeed the overall decision to throw their hat into the market.

ZDNet also mention the fact that IBM LotusLive offers an extensive range of services, and I go would as far it say it’s one of the most extensive ranges in the whole software-as-a-service / cloud-based market – a choice of e-mail, integrated collaborative services and web meetings.
