I read the name first because it is written in bold above the post so is the first thing my eye sees.
I also find, having been on GN since inception, what 10 years ago? that I do recognise names that keep occurring, especially if they have a 'speciality', politics or, in relation to COVID, pedal unsubstantiated conspiracy theories.
But mainly I just recognise names. Over the years, with regular posters, i do recognise those with whom I seem to share a lot of opinions - and those, who for any reason, consistently disagree.
I am not good at recognising style, why should I when the first thing I see is the name.
I am interested in people, the names they choose and who they are - I have also made several good personal friends through going to GN meet-ups.
