You're coming at this from the wrong perspective.
That doesn't surprise me in the slightest.
Anyway, thanks for the advice, all.
Unfortunately, despite all the helpful pointers, I can't limit myself to applying for jobs to which I'm specifically suited (keeping in mind your comments about discarding those who just list generic skills), because such jobs which are also within my travelling distance won't come regularly enough to please the jobseekers' people - I have to churn out applications to any and all jobs I could possibly have some sort of a shot at, which means sending CVs all over, whether they have a realistic chance of passing through the filters or not. Really, for many of these jobs, there's no way to make my CV part of that select group that actually gets anywhere, but I still have to send it.
