I just installed Cat2tag a wordpress plugin to add folksonomies to Wordpress. Though I’m not yet a power blogger (i.e. I don’t blog multiple times a day or for that matter multiple times a week), as a power del.icio.us and scuttle user, I can immediately appreciate the value of being able to create tags on the fly.
My only gripe is that I would love it if Edmundo could make tags comma separated instead of space separated. I like the multi-word categories names without underscores.
