These services are more for “off the top of your head”, “what are you thinking/doing” type posts. And, already I’m more frequent at posting there, than on this blog.
One of the problems is that most of the people I’m following on both services are in the US, meaning they’re quite when I’m online… and active when I’m asleep – meaning you’re not part of a conversation – you’re just playing catch-up.
The other problem is “who cares”? That is, who cares what you’re doing right now?
Lots of people are getting excited about these services, not just in the tech-head circles, but even in education circles. Not in my education circles – Twitter is blocked.
