But then - a few bucks a month turns out to be $5/month, and that comes with a limit of 300 searches/month. That's an average of just 10 a day and while in practice I probably wouldn't actually hit that limit it's uncomfortably low enough that the added fiction of each search having a tangible cost is just a non-starter.
I can't help feel that when the competition is free - and on precisely the recognition that people don't pay for search - that a more aggressive $2 tier for personal customers could get a much wider penumbra of folk such as myself over the line, rather than be yet another $5 service that when applied consistently actually start to add up.
