Hm. While there are a ton of funny things I've loved on the net, I think the best thing to me was this post : http://hyperboleandahalf.blogspot.c.....epression.html Best on the internet to me, because it best described something I've always had to deal with (feeling alone in it too), and using it to explain depression to others helped them figure out how to interact with me in relation to it better. Plus it was a nice outside view and allowed me to reflect and work on my own. So, kinda of an odd 'best' considering there are also youtube channels like zefrank1's which are have funny stuff and really inspiring stuff (close second) but I can say that post helped me make better changes for myself and generally speaking I haven't had a severe bout in a long time, which is the best thing for me. Something I remember over time and sometimes re-read to remind myself of where I've been and fight harder to not go there again. So a holistic best thing on the internet to me.

Thanks for sharing. I agree it's well put, and enjoyed the read.

Wingsuit proximity flying. Its insane. Its awesome. I can't get enough.
As for the best...I don't know. I've seen alot of awesome stuff. I'll just go with a Wingsuit vid for now. This video is put together very well. I also love the speech by Bruce Lee at the end.
