How many blogs is too many?

I regularly post to three blogs. This one, which used to be work related, is now sort of miscellaneous. I try to keep my other blog @the.coalface, which is a multi-user WordPress blog hosted at my University, focussed on my reflections on my experiments with education technology. And I am a regular contributor to the Swansea Learning Lab community blog, where I typically re-post interesting items of e-learning inspiration and that I find in my daily trawl of my RSS feeds. 

However, it seems that I could do even more. As a member of the [Eduspaces](http://eduspaces.net/cpjobling/) and [Classroom2.0](http://www.classroom20.com/profile/ChrisJobling) community networks, I have two more blogs available to me. As an academic I have an entry on [Academia.edu](http://swansea.academia.edu/ChristopherJobling) and could have a blog. I [microblog](http://www.twitter.com/cpjobling) on Twitter. I [share favourites](http://www.google.com/reader/shared/12981735514196780717) from Google Reader, my [delicious bookmarks](http://delicious.com/cpjobling) and some of [my photos](http://www.flickr.com/photos/cpjobling/) on Flickr. I even have some module related blogs in Blackboard for some of the courses that I teach. So is this all too much? Am I spreading myself too thin?

I have dabbled with various ways to aggregate all these strands of my life on line. For example, I have created a [Swurl page](http://cpjobling.swurl.com/), a [FriendFeed](http://friendfeed.com/cpjobling), a [Tumblr blog](http://cpjobling.tumblr.com/) and a [Netvibes public page](http://www.netvibes.com/crispyj#Latest). I even have a [Yahoo! Pipe](http://pipes.yahoo.com/pipes/pipe.info?_id=Wnwc21Am3BGdl8vPBx2yXQ) which aggregates some (but not all) of these and generates an RSS feed!

So which is the real me? Which should you follow?
