The comments on the last blog were very useful. Through Plurk, I have been put in touch with Carol Daunt Skyring and have been looking at her wiki which seems to make it possible to do the things I was complaining about not being able to do in a blog! I have now set up a wiki – very embryonic at the moment – and am already finding it useful as a repository for stuff. I suspect it may take over from OneNote in some ways, except OneNote does enable me to grab emails and webpages and scribble on them.
Will keep under review my use of the various tools and their pros and cons.
