<p>To a greater extent than here, SO seems to divide up into mostly independent topic areas, though individual questions might cross several such topics that usually don't sit on the same question. </p>

<p>In my case, I read the <code>r</code> tag there, and rarely look at anything else, so stackoverflow looks to someone like me like a largish but quite manageable site with questions on R. Sometimes I read Python questions (but can't answer any - it's a way of trying to learn more). On rare occasions I venture into looking at other tags.</p>

<p>I imagine most people would look at a wider range of tags than I do, but would still keep themselves to only a few.</p>

<p>Here on CV, I don't limit myself by tags. There are certainly some tags that I'm not qualified to say much about, and topics I'm not actively trying to answer, but I try to make sure they all show up when I look at the site. That's partly because stats questions are much less compartmentalized than typical SO questions (and partly because both my interests and background are substantially broader). It's the same when I go on math.SE (though the topics I'm qualified to answer on there are more restricted). Since math.SE has quite a bit more traffic than here and it's not quite to the overwhelming stage there, I expect I'd be able to see a substantial growth in traffic here without changing that habit very often.</p>

<p>However, if the volume were multiplied by ten, I imagine I'd pretty much have to cut that "read everything" down a lot of the time, either by searching on favorite tags or by using the ability to ignore some. </p>
