How would you like to Web 2.0 it up in your email signature? Before you say no, let me remind you that the email signature is one of the best places you can advertise yourself, your brand, and revolutionary new company that no one has heard of (yet). Don't forget that the very beginnings of viral marketing started with email, and signature files.
Now that I've clobbered you with buzzwords, take a gander at the MyBlogLog introduction of a new feature that can really make pretty your signature.
It contains all the important contact information, a snapshot of a page from one of the communities you belong to, and all those clever little icon links to your profile at just about everywhere. It even has a place to link your RSS feed with one of those cute little orange icons.
