Missing the in video resource intro; Removes comma in date with no day

[randomecho]

The "Git Videos" intro paragraph sounds like it needs a "the" there.

And is a podcast a podcast if you watch a video with it? Isn't it then a vodcast? Or vidcast, however the puritans have it now.

@randomecho Webcast, webcast, webcast! :)

Thanks for the fixes as always.
