Top ten popular websites I’ve never understood and/or even looked at or even heard of

Yes, I’m obsolete, middle-aged and lovin’ it.

1. Reddit
Most of the internet seems to be run by kids for kids.
2. TwitchTV
Want to watch a busty, hot Canadian woman playing video games? Of course you do. Apparently this is now the most logged in website ever (someone told me; don't know if it's true). I literally hadn't heard of it until yesterday.
3. imdb
I've yet to find a decent film website.
4. Pinterest
Random, pointless.
5. TripAdvisor
Every month, 456 million people visit Trip Advisor – but not me. I sort of knew what it was, but have probably only visited it once before (to research writing a previous post). I would never read a review and go or not go somewhere based on it. Like with Amazon, if there's a thousand reviews saying how amazing something is (which I'd always be sceptical about anyway), they'll also be lots saying how rubbish the same thing is (which I'd be more likely to believe). So how to decide? Go there and make up your own mind.
6. Rotten Tomatoes
I think it's a film site run by teenagers.
7. LADbible
Just the name makes me want to puke.
8. Live
Anything Microsoft related isn't worth visiting.
9. Live Jasmin
Popular porn I think.
10. Office
See 8.
