I thought this was quite amusing.  Just another clever html email signature tool you might say - but makes it easy for a normal person to put it together.  It can bring in your last tweet and last blog entry - along with some other social media choices - making it easy to spread your brand.   I would imagine businesses would like something like this for their email signature.  If you are an SEO guy - you might wonder why they make your links rel="nofollow" - which tells google not to follow the link - I like all the juice I can get.  Its a browser plugin - so its a snap to install.   The app isnt yet available for IE.  After adding features to your signature - it does the rest.   The signature shows up in your gmail or yahoo email automatically.   Join the party at http://www.wisestamp.com/
