for me its the entire end-to-end process that could be quicker and easier.
- create a unique/random ID for registering on a website
- remind me somewhere of the link between that website and the email address. especially relevant if its a random text string and not andyr+ebay@...
- create a personality with similar details for replying to any emails
- arrange to folder emails if so desired
- manage expiry of address on a date, or after a number of emails, or be able to kill manually (this should apply to personality too)
i think if it included all that, along with Eric's magic spiderman-firefox plug-in then my "personal" email address would be even more safe and spam free in future.
