I have about 300 followers, but only half-a-dozen who tend to comment at all. One being 'Mr Highlight' Perlmutter, of course!
Seeing the follows on Fanfiction. net is even more amusing, since people often follow a single story, rather than an author. Even ten years after I wrote it, I still get new follows for Rediscovery! But oddly, not that many of those follow or favourite Flight of the 'Vigilant'
I don'y deal in algorithms and such. I stick to that old Yorkshire saying:
There's nowt so odd as folk. Bar me and thee, And I'm not so sure about thee!
