Good point, but it's still an interesting observation. 37signals was everywhere in 2006, and now, not so much.

I'm not sure how that translates to anything meaningful, or whether it's just that their message has been received by the audience already.

Personally, I think they have reached a work threshold for their team. They haven't expanded all that much from the original core group, (not that they want to) but they've increased the products they service. There are only so many hours in a day.

I'm actually interested in seeing what happens to them in terms of their "keep it small" mantra and the obvious desire - and need, considering their marketing prowess - to introduce new products.
