Woops sorry Bernadette, I stopped reading every single page after page 21 :\

Nos, it's been a few days and it's mostly to share your activity or to see what others are up to. I like to comment on things, so that's what I've been doing so that I can better connect with the people on my Twitter feed
I don't use mine that much - mainly when I am on my computer, or ipad and, much like the forums, I tend to browse stuff more than post. It is good for contacting companies with queries or customer service stuff. I generally delete my tweets when I have got an answer from them.
I can also use it to stalk my daughter! She hasn't blocked me yet
I'll have to look up sightings - never thought to do that.
