Have to say I'm liking my blogs more and more now we have keyword tagging.
I know Blogger was late with this feature, but I'm starting to find that it changes how I think about my blogs. I feel far more confident writing for the "long term" in the blog. In the past I considered ThoughtStorms for anything long lived, and blogs for the ephemeral. These days, really ephemeral stuff goes on Twitter. I'll use blogs for quite serious essays and more focussed stuff. And while ThoughtStorms is meant to be for the longer term stuff, it has, of course, got quite out of date.
I may be revisiting what I said over on ThoughtStorms:WikiLog referencing Bill Seitz, and in many debates with Chris Dent and Eugene Eric Kim.
Briefly I've been saying that you can't merge wikis (which have semantically meaningful "pagenames" as their addresses) with blogs (which have semantically meaningless dates as their addresses) or "purpled" paragraphs (which have semantically meaningless codes) as their addresses, because working in wiki requires the fluent link-making that semantically meaningful pagenames give you and you don't have.
Well, I still think that's kind of true ... but it's also damned useful to have ways of bringing together stuff that you've put on wikis and blogs. (And twitter). Perhaps we can't dismiss the attempts to produce hybrids so easily.
Maybe tagging can help. After all tagging doesn't give a unique ID, but tags are a) semantically meaningful, and b) exist in both worlds (on blogs, and as "CategoryCategory") in wiki.
Update : Interesting to see Chris Dent experimenting with something new.
