Customer of VidCaster? I don't think so, check his previous comments:
"I happen to know Kieran Farr quite well. http://www.vidcaster.com/ was one of the first companies in our Co-op incubator. And, I have no doubt, that Kieran is going to be far richer than some reporter who still makes his living writing for a company that think that selling yesterday's news written on pieces of dead tree is a viable business model."
Pardon me, I inferred from the hackersandfounders.tv site that uses VidCaster was an independent venture and not by a co-op incubator or anything.
The main point I have against this article are that
1) It's poor journalism in that little research into competitors was done. Leena Rao doesn't seem to be aware of the many competitors who have been in this space for years (like VidCaster) but only a few like Ooyala and Brightcove (which TechCrunch uses iirc).
2) Lack of disclosure as to the relationship between TechCrunch and YC startups is a problem. There's an inherent bias without full disclosure.
iamelgringo is a customer of VidCaster, not a competitor of Vidyard.
I also don't understand your ignorance comment. Vidcaster and Vidyard are two competing companies.
iamelgringo brings up a salient point I think, YC companies get a disproportionate amount of coverage on TC as compared to other startups.
