Edit: below composed prior to the above post.

I think Teylyn's point was simply that whether intended or not use of forename only references implies a certain familiarity.

My initial point was more to do with referencing specific links ie don't presume those for whose benefit you're posting will be as familiar with the named reference as you are (I didn't know to whom "Kevin" referred).

I do confess however that like Teylyn I prefer people keep all references on the board as formal as possible irrespective of personal association.
