I've im­ple­ment­ed some sort of tag­cloud on this blog. It's not re­al­ly a tag­cloud since I don't tag my posts, but it looks like one. The tag­cloud is gen­er­at­ed by count­ing the oc­cur­ances of all the words in all the posts, and then stop­words and oth­er words I think add lit­tle val­ue to the cloud are fil­tered out. There are also some stem­ming is­sues re­solved like putting "play­ing" and "play­er" to­geth­er with "play". From the re­main­ing words the thir­ty or so with the most oc­cur­ances are then fed to HTML::TagCloud, and that gives a re­sult like this:

Not us­ing real tags means every oc­cur­ance of a word adds to the sig­nif­i­cance, so it's not based on how many posts are about some­thing, but how much con­tent is about some­thing. It also means the words are lim­it­ed to words, so "open" is show­ing up, but not "open source". That's prob­a­bly why "OS X" isn't in that cloud. But it's nice to see "fri­day" and "week­end" show up, and "Rot­ter­dam" man­aged to bub­ble up while "Am­s­ter­dam" didn't make it.
