"What is Xanga?" 

Xanga needs to redefine itself.  It currently defines itself on the portal page as "a community of online diaries and journals."  

Of course, it's a community.  There's no question about that.  But of online diaries and journals?  hrm.  My journal meets your journal.  My journal likes your journal.  Your journal finds my journal attractive, too.  Our journals bond and form a community!  A community of journals we have thus become.

No, I don't think so.  Any assemblage of diaries and journals, in and of themselves, will never be more than a collection.  But Xanga is more than a collection.  It is a community. It's a community that has  formed itself historically largely through the sharing of online diaries and journals. 

But, that still leaves the question, what is it a community of ? 

Would-Be's?  Wanna-Be's?  Writers?  Voyeurs?  Lonely Hearts?  Friends?

moniet, in response to my challenge above has responded in a comment:

"I think Xanga has bigger problems than it's definition of itself."

My response to that?

I don't see Xanga as having that many problems.  I do see it as having challenges and opportunities to embrace.  In order to embrace new challenges and opportunities, it needs to constantly redefine itself in light of the choices it has and shall make.

"What is Xanga?"  is a question whose answer has changed over the years and will continue to change, to evolve.  I'm merely pointing out that a change, a newness, in the response to that question now seems timely due.
