Linking "Member since" info to user's first Plurk?

I can't remember my first Plurk, especially since it's been nearly a year since I signed up. Granted it may be something as mundane as "Hello Plurk!" but it would be nice to revisit it in a quick way.

My suggestion would be to make the "Member since" information in a user's profile clickable, with the link going to a user's very first Plurk... or at least link it to a somewhere where the users can have a way to browse through their old Plurks?

Thanks.
