I still find it a little disorienting since I'm not used to it, but I really dislike that the notebook defaults to "all languages" (unless I'm missing something that restricts this permanently) so usually, the first handful of entries I see have nothing to do with either my native or target language.

No, it sucks and is a waste of time.  That's why I'm here.  -.-.  Sarcasm out of the way...its fairly new and there are a lot of nationals you can hook up with.  It's really to me a great way to meet people and get some free language lessons, while also helping someone else learn your language.  I think the site is cool...though it would be nice if I could add more than 2 friends a day -.-.
