Chon-bae S.

Been going to Youtube as far back as December 2005; then started uploading videos a few months later in 2006.
Been through plenty of website revamps, policy changes et cetera over the years.
Still remember such phrases like "Press the link on the side-bar/description" which has long since moved down. Learned plenty of subject matters from others which has been fantastic. Liked the fact the 10 minute limit runtime per videos increased. 360p resolution increased to HD as technology progressed.
Like many others however... I believe the YOU in youtube is pretty much gone as it focuses more on corporate content. I have to search hard for the old vibe in face of it all. Aside from that I find it a good website.

Found ustream via links to peoples live broadcasts.
I use Ustream's android app to record/broadcast events as they happen with my smartphone.
As for the website, it is feature-rich, it'll be more-so if you pay. I never payed for ustreams services so i'm stuck to basic, i'm fine with that. With the basic no pay service. You'll have advertisements on your pre-recorded videos or livestreams, video will be limited to VGA 640x480p resolution, inability to auto-save a stream, and will have 10 gigabytes of storage for those videos. I don't mind those limitations since my phone cannot record in HD. Never had a problem with ustream service yet. Overall my experience is positive.
