Yeah, its spammy, but spam from a single source is pretty easy to manage. As a consultant and writer it would be much more difficult to do my job without the ubiquitous ability to contact people at other companies easily.

I'm not saying its the best, but when the alternative is nothing at all, I can't really fault it for doing what it needs to to make money.

Also of note, a 25% reduction in sales and marketing expense would have made it profitable this last quarter, so evidently there are plenty of ways it is adding value to others.
