<p>This is moderately different to my title -- short story is that I'd like to be able to upvote questions/answers on StackOverflow, but am likely to only ever participate interactively on CrossValidated. I hope this is an OK topic for meta.</p>

<p>I'm a biostatistician -- so I use StackOverflow quite a lot for advice on various bits and pieces of programming, and would like to upvote the useful help I find. But I only have reputation in CrossValidated, since this is where I can usefully help people out with answers (I hope) -- I wouldn't be much use on StackOverflow. Also, pretty much every question I might want to ask on StackOverflow has already been answered (which is good for me, and why I'd like to be able to upvote things!)</p>

<p>Anyway, I'm wondering if people have ideas about how best to approach getting reputation on StackExchange, given that I'm very much a browser/end-user there (and don't want to jam things up with questions that have already been answered) -- I do often get useful help from answers that seem to be orphaned, with no upvotes.</p>
