diversity

I'm tempted to ban all or most message templates. They tend to be completely ineffective. New user templates tend to come off as impersonal, robotic, and unwelcoming. And templating the regulars? It's a disaster, for exactly the reasons you mentioned.

It's been a while since I've been on Wikipedia... but I can't remember the last time I saw a template on a user page that was nice.

Ban message templates oriented to new editors at least.

I'm not supportive to the {{welcome}} used here (wiki strategy) to welcome new contributors.
