I think this is cool, even if no-one else does! Got an email today from an old colleague wishing me Merry Christmas, nothing out the ordinary there, but, when I looked at the details in gmail the email address I saw was “[email protected]” with a little note “(Yes, this is you)” by the side of it. When I clicked on the find out more link I learnt that gmail ignores dots (.) in usernames. So, when all those people have asked “all one word?” on me giving out my email I can now say no, first.last or firstlast. Mmm, geek.
