A filtered thread index as proposed could be a recommendation system
according to both descriptions posted, although it depends how one
interprets "suggest", "support" and so on, and how much
personalisation one believes is needed to be a recommendation system.

One can just as well see many drawbacks by looking at more general
"collaborative filtering" research - or even out into more general
population clustering work to see the reasons for the drawbacks - but
it's a bit older, so less of it is online, so I didn't refer to it.
I'm pretty sure that someone would react to the obvious problems in
using an unpersonalised filtered thread index (which is a
collaborative filter, isn't it?) by personalising it to make some sort
of simple recommendation system, wouldn't they?

Nevertheless, I now wish I hadn't tried to skip the above step,
because it's resulted in this pedantic subthread.
