A year ago it was quite common to see Mahalo show up in google searches. They're in decline.
Hate to bring up digg, but its in a positive light rather than my usual bitching. When we were around 4 million uniques we had 4 people (not actually employees, this was pre-series A), and Calacanis tried to buy us for $5 mill (almost all of it subject to earnouts). Rough subjective cash estimate of mahalo valuation based on his own offer to digg - half a mill.
