<p>A similar thing happens with the "clustering" tag on SO. One third want to load-balance their web server, one third are about database clusters, and one third is about cluster analysis.</p>

<p>IMHO stackoverflow needs some "this tag is ambiguous, choose a better tag" function. <em>People do not read tag descriptions</em> (the Android app doesn't display them anyway). If a user types "kernel" he should have to choose from KDE, kernel-trick, etc. and not be allowed to use the ambiguous version. (Aliases don't work - on SO clustering is aliased to cluster-analysis, and we get plenty of mistaggings there. Instead, multiple alternatives should be offered: load-balancing won't turn up when a user searches for clustering either!)</p>
