But then again: that’s a rule of the game – and if your aim is to promote semantically rich urls in your Twitter-feed, you just better keep them below 30 characters. It’s hard enough to limit the praising of a given link to 140 characters.

So, what are the more concrete implications of this?
Well, looking at my own permalinks (that have annoyed me for some time now) – I now have another reason for skipping those non-semantical parts of the permalink: http://blog.heick.nu/archives/2008/04/. That’s 38 characters right there – and I can be pretty damn sure that any link from this blog posted on Twitter is going to be tinyurlified…
Still even if I (when) change my permalinks to the shortest possible form: http://blog.heick.nu/%postname% – I only have 10 chars to do with.
In any case – In the future, I might just start shortening my urls to make them Twitter-friendly…

Is that called Social Media Optimization? SMO?
