Acquaintances list (aka "You're my friend, but not my best-best friend, okay?")
Short, concise description of the idea
Like the Friends list, only my list of Acquaintances won't have access to my Friends-only posts.
Full description of the idea
There are lots of people I run across in my lj browsings that I think are interesting but I don't necessarily know them well enough to give them access to my friends-only posts. So I don't list them as a friend. But, then since I don't know them very well, I can't find them again later to read their interesting journal. An Acquaintance list would be all the interesting people (or communities) I want to keep track of. I would have an Acquaintance Page just like a Friends Page-- which can be a major drawback with server overload. Maybe a paid user only feature?
An ordered list of benefits
1. Separates the people we know (Friends), the people we want to know better (Acquaintances), and the people we've never met.
An ordered list of problems/issues involved
1. Just like loading of Friends lists clogs up the servers, so will the loading of Acquaintances lists.
An organized list, or a few short paragraphs detailing suggestions for implementation
1. I guess it'd be done the same way the Friends list is made, only Acquaintances wouldn't have any special permissions to view posts.
