The discussion on blogs over on David Maybury's blog has thrown up a lot of viewpoints as to how writers can achieve recognition and the divide between whether blogs/websites/links can further that end seems to show that there are no easy answers either.
It seems to boil down to the difference between hard copy and soft copy.
For myself, blogging has been about bouncing ideas around, but mostly its about blethering into the blogosphere, letting off steam and generally having the blog equivalent of a scream jar in a library, like in the cartoons - you scream into it and run outside and open it. But I like having some record of what I've thought, even if it does make me squirm further down the line.
Either way, I'm grateful to David for asking the questions!
