Some time ago monks were prevented from Front Paging their own nodes as this was felt be be a form of XP abuse. IMHO a new abuse trend is to reply to a node, and then Front Page it, which has a similar effect.
Oh come on. If I find a node to be particularly interesting, I am likely to front-page it - because I think other monks should have it shoved in their face. But also I am *far* more likely to reply to nodes I find interesting (and hence which I front-page) than nodes I find to be boring and irrelevant. If you think it's bad to reply and then front-page, I guess I'll just have to front-page and then reply instead :-)
