<p>I only find like 12.5% of xkcd posts funny. =/</p>
<p>If you find ~12.5% - 25% of posts from a particular blog/forum funny or interesting, do you consider it worth your time?</p>
<p>(hm, xkcd is a lot less frustrating on google reader since google reader tends to distribute your attention among multiple posts rather than one post so you don’t end up swearing to yourself “i never want to look at this blog again” after a string of non-funny (to you) posts.)
I don’t know though. 12.5-25% is definitely a success in my terms.</p>
