I think I may have an answer to your broken links problem. Putt was talking yesterday about requiring new accounts to have 100SCP or something before they are allowed to post comments with clickable links. It is a tool to discourage spammers because they will never hit 100SCP or CCP and will therefore never be able to post clickable links. I don't know what the current requirements are or whether Putt's changes have already taken effect, but safe to say that your issues are because this is a new account of yours. I think you will find it will resolve itself as you get a few more upvoats. For what it's worth, your YouTube link here is clickable for me.
