There is a tradition of keeping “work blogs”. Scott Wilson’s workblog is a touchstone for this kind of online identity and presence. Scott writes a lot on identity and presence and education (and here and here). This is written in my workblog. I feed stuff into here from my Posterous account. I use Posterous to feed my other work Blog, Developing Themes for the JISC Institutional Innovation Programme support, synthesis and benefits realisation project.
If any new Lecturer at Brookes wants a work blog on our WordPress MU development platform or a wiki space on our in-house Confluence server. Just give me a shout.
