Recently I copped some flak regarding my Twitter usage policies. So now we've all calmed down I thought I'd whip the storm up again by explaining why and how I use Twitter: this technique might be useful for you.
When I started on Twitter I followed quite a few people but I found the flow overwhelming. I'm not a compulsive reader and I don't like to devote too much of my scarce time to social media, so I'm never going to get through them all.
