I sign up for a lot of online services. Some I abandon quickly, others, like bloglines, I use for years before moving on.
I'm more aware now of the security risks of leaving account information in corporate servers that may end up in bankruptcy proceedings, perhaps to be purchased by the Bank of Ferengi.
So these days I try to cleanup when I quit. Today that meant Bloglines (no account removal option) and Ustream's Watershed ...
... After my initial testing I was never able to get it to work. Tech support was responsive, but it didn't clear up the trouble I was having. I decided to step back and wait until there are more players in this market. Then I discovered there was no way to remove my account information...
I can delete the "account", but when I log in it still shows my sign-up information and the "valid credit card" is still there.
So now I have a new resolution.
I don't sign up for services that lack an appropriate account deletion function.
If we all followed that rule the world would be a better place.
