Thanks for such an informative post Gareth, gonna look into this, to be honest I've heard of Twitter but don't really know much about it.
Isn't it mainly for youngsters or have I got the wrong end of the stick with this? For example, am I going to bump into the buyer for Tesco's stationery on there or other professional businesses which lets face it are the kind of people that we want to network with.
Another problem I find is trying to write SE friendly content in all these different places without duplicating it, kinda running out of topics now to be honest...and fed up of typing
However, you have to put in the hard work so I may just open a twitter account to see what it's all about.
Hopefully some others will air their views.
