A subject which is intriguing me, recently, is that it seems my own attitude towards Twitter may not be the quite the same as many others. In particular, whilst almost everyone seems hell bent on increasing their number of 'Followers', my own approach is almost the complete opposite.
For example, apart from the fact that it involves trawling through pages of frequently irrelevant dross, I really don't see much point in accumulating vast numbers of 'Followers' for no reason which is obvious to me. Furthermore, as exemplified by the words of W.S Gilbert, there was a time when it was considered inappropriate to become too familiar with anyone without having been properly introduced. Nowadays however - and especially within social-networking sites - it seems almost de rigueur to reveal quite intimate details at a very early stage in a 'relationship'.
So - and without wishing to sound too pompous - I have always limited those I 'follow' or by whom I am being 'followed' to people or organisations I know, to whom I have been recommended, or are of my own choosing. In making these observations, by the way, I would be interested to hear different points of view.
