it always looks like it's peaking if your growth is hyperbolic. whether or not they're idiots or geniuses is determined by the market.
but if I was running twitter I would certainly take $150 million in cash. If you still want to run a company well now you have cash and a success under your belt. Funding should be an order of magnitude easier.
"it always looks like it's peaking if your growth is hyperbolic."
Sure, but the fact we're even discussing $250m valuation for a company whos only real worth seems to be its users and possible future profit, should be a good pointer that this is a peak. Much like Facebook peaked.
That article made it seem like it was about $150m (at the more sane $5b Facebook valuation) stock only. I wouldn't take that if I owned Twitter.
