I’m not sure how that would work, but I would assume that it should be feasible to alert 43T users that someone has a suggestion for them.
Another cool thing, I think, would be to allow 43T users to add it to their list of things.
Not so sure how non-users of 43T would get notified. EDIT: I just ran across the suggestions.yoursite.com. Nifty feature. Not sure I could use that much suggestion making at my site (barely more than a vanity site).
