I don't think this is a tough question to answer, but a DigitalPoint Forums member asks whether YouTube is better than Google Video for sharing videos.
Part of me says to submit my vids w/ YouTube b/c that's where all the action is and videos submitted via Google Vid should show up there anyway. The other says I might get a higher number of views if I submit them to Google Video.
I'm not sure where he suspects that higher views come from Google Video, since the only URLs I see shared on the Internet are really YouTube URLs or embeds from YouTube in blogs and articles.
Most members have settled upon YouTube because of the community awareness, which is exactly what I also encounter. In light of yesterday's findings that Google Video sends logins on an insecure HTTP protocol, YouTube might very well be the best choice all around.
As far as uploading to both Google Video and YouTube, why not? I don't think it's a spamming tactic at all; the audiences seem largely different in my experience. And Nathan Weinberg does it too.
