Having worked hard to build the TweepsMap project, launching it was a little tricky. It was like starting up a new fire, it catches on then it dies on very quickly. There is a certain formula on how to attract others to check out your service, without being too intrusive.
Anyway, throughout the process, few blogs featured TweepsMap on their sites, including Google Maps Mania coverage TweepsMap, few other spanish blogs, but I did not expect how large the effect of Mashable on the number of visitors, as soon as the TweepsMap article was published our servers were overwhelmed, that we had to beef them up, and the wave continued for days. It also had a ripple effect that many other major blogs would write about the service.
Thanks Mashable!
