It does have its uses. It was bizarre that the other evening at home I had to read on Twitter that it was snowing in Eltham, causing me hurriedly to look outside and see that it was true!
There are quite a few active local Tweeters - for example, @darryl1974, @AdamBienkov, @nigelfletcher - some of them count as Twitter aristocracy. The trouble is that you naturally want to sign up to follow the ever more interesting Tweeters that you comes across through other accounts, and then you end up with tons of tweets - some good, others less so.
It was a co-incidence that I've signed up at the time when the value of blogging is being questioned, and when the legendary blogging guru Iain Dale has announced he's giving up blogging. It's interesting though that many of the most successful Tweeters are also prolific bloggers.
I have found that Twitter and Blogging are quite different, both as a producer and consumer. Each has their place at the moment, but for how long? Will the quick fix of the rapid-fire 140 characters satisfy over the longer, more leisurely meal of a blog post?
