Obviously not all bitcoiners use reddit, but just how many do is unclear.

So if everyone here would add "r/Bitcoin" or "reddit" to their node's uacomments, it would be handy to try to gauge this.

Simply edit your bitcoin.conf file and add a line:

uacomment=r/Bitcoin 

or

uacomment=reddit user 

(Note that you can have multiple uacomment fields in your config file!)
