 Is viral marketing effective for sites/apps with high IQ users?
nostrademons: I get the opposite impression: smarter people are more likely to recommend a site/app to their friends, both because they tend to have broader circles of friends and because they like the ego boost that comes from knowing about a site that their friends didn't.They're just more discriminating: you have to be genuinely useful, because they lose face if they recommend a site and their friends try it out and say "WTF are you telling me about this for?  It sucks!"  Actually, that applies to people of all IQs, but smarter people are probably more likely to apply the "This sucks" label to a site.
