Twitter has started its mass roll out of lists and I just created my first of public sector people (and hangers on) I follow.
I laughed out loud when I clicked through to see I'd been already added onto 28 existing lists - and what those list titles are. According to some of my followers, I am alternately:
Lists are really useful for finding others around a specific topic. listorious.com is a good place to find ones already created and there's ones for top egovernment people, government bodies etc.
The one I've created for UK public sector workers and contractors I grew through following links to other's lists in this area. Listorious has several others created around the 'government' theme.
I haven't analysed this but I've noticed that from following my list others have added people found there to their following and hence made connections which they might not otherwise have made.
