I can agree with his numbers.....
The wife likes to upload videos of the kids doing things......eating speghetti, crawling, first steps, walking, driving my $3500 zero turn radius mower into a tree. You know, kids stuff.
As an alternative, I have her upload them to youtube or her channel me site, and she sends links to those videos to her friends, or embeds them on her personal site.
I guess I see it as why use my bandwidth if there are alternatives. I do have my own server and bandwidth, but I find this easier then monitoring whether or not her friends and family are eating up all my bandwidth watching my daughter smear cake on the dog's head.
