An interesting idea, that in time your reputation (REP) on the Blockchain will trickle down through out the Inter-Webs.
And actually mean something solid.
"So you want a Mortgage, Hmm, I see you have a very low Blockchain REP. Tell me exactly how you are going to rectify that?"
On the extreme side, I hope we don't go all Japanese and have to commit Blockchain Seppuku if our REP gets Dishonoured;D~
