Sorry to play devil's avocado here, and my understanding of the law is of course limited - but - I believe while you are fully within your rights to film someone in a public place, I think there are different laws in place regarding their broadcast.
Hence when you see TV shows and there is filming on the street, sometimes you get people's faces being blurred out - I think the broadcaster requires a consent form to be signed for the material to be broadcast.
Worth investigating I guess.
When I was working at the hospital and the Beeb were filming there they would use release forms, yes. However this was due to it being classed as private property and members of staff and public being in a difficult and sometimes emotional circumstance.
On the street its different. You only really need a release for certain commercial and advertising scenarios (for example the ads with the kleenex where people chatted on the sofa, and the ad with the running machines in the street where people looked on were staged to avoid this, others far enough in the background didnt need a release)
If you're submitting photography (or even video thesedays) to library agencies they often stipulate release forms, but meerly to cover their back and out of a business policy (as already said Youtube is taking a business policy)
I think you have to remember that what Mags, I, Thomas and others do is a form of blogging, its generally "recreational".
