No doubt, I don't have to inform some one who's been a FReeper since 2005-06-11 of this, but your FRName at the bottom of all your posts is also a link to your FRProfile page... '-)
There you go, you went and truly made me Laugh Out Loud!
Of course you're absolutely right, and I use that feature myself daily to find out who I'm conversing with.
I occasionally post a link to the "Computer" section of the profile right in the comment text because perhaps a) the comment context suggests doing a bit of 'splainin', and b) not everybody knows or remembers about our handles being profile links.
The other factor is that more often than I like, I get labeled a Mac fanboi by Windows devotees, a Windoze fanboi by Mac-heads, a commie-lover when I say something nice about Linux, and so on. Pointing them at a clickable link is less pompous than "You have no idea who you're addressing", and way more polite than "Back off, Jackhole".
But yes, you're quite correct. ;-)
