• Q: How useful is the Learning Xchange before it achieves enough users ("network effects")?
• 
  A: Admittedly not very... so please consider adding your posts, and telling others to please add theirs as well. But at least for the early days, users probably shouldn't get their hopes up.
  
  Our plan is to:
  
  1.) First spread the word to public libraries, which we view as a natural opportunity for connecting people already looking up books by title;
  
  2.) Provide specific ideas and suggestions (on our "Search Results" page), as to how you might go about finding a match if our database doesn't yet provide any (or sufficient) search results;
  
  3.) Establish a help-forum in which users suggest ways for locating learning matches.
