Do you mean to imply that patent trolling shouldn't affect how we develop software? I hope you don't, because then you're suggesting that we remain at the behest of those who set patent policy. No other way to say it, that's just a bad plan.
I feel like your more recent question is not directly related to the previous points (so maybe I'm misunderstanding), but I'll answer anyway: no, I don't think hackers should worry too much about patent trolls when building stuff (or else the trolling is working and limiting creation), but I do think hackers should make a stink when patent trolls do their thing--especially when they do it to the little guy.
