Your Canadian and your experimenting with .co.uk??? and .in??
How shameful, lol...
There are ALOT of .ca's dropping and available nowadays. Grab some of them. Same goes for .com and .net, I see more and more becoming available..
You should be okay with "boob"
That domain "BoobTube.in" is worthless unless you plan to develop and SEO. Any extension can work for these types of sites as long as you get visitors. I'm getting quite a bit of traffic on a .BZ domain of mine.. .BZ! thats worse that .co.uk...
Good Luck Dude!
GO CANADA GO!!!!!
