Do you think a social news site for birdwatching would be a hot acquisition target? or get a few million funding? or turnover millions in revenue? - I have no idea. You might be right after all. I do think that if well executed, it is in the category of something people (birders) want.
When I was into it, I bought a few books, a nice pair of binoculars, took a trip to a National Park in the north of India in the middle of winter and often woke up at daybreak to watch birds. That last thing required real commitment. I guess we'll leave it at that.
