Anytime you have 300-500 million people on something, I will go out on a limb and say that is pretty broad! Even the automakers and such on commercials are saying follow us on twitter and Facebook. I think its about the most intelligent decision one who wants to promote something could do.
VCTY GOOD TO GO, but Twitter is not a non-exclusionary form of media.
In my opinion it is exclusive by its very nature. Although anyone can sign-up for it and be accepted by default as a follower of a particular tweeting company, the fact, that the general public has to go through specific steps to be informed of news about any single company, makes it exclusive to only those interested in the particular company.
The same can be said of any other forms of public disclosure that does not resemble the newswire format. Even with conference calls, although not all information has to be offered, the conference call itself has to be published on a newswire to keep it from becoming exclusionary to those only interested in the company.
With that said, I think VCTY has met that criteria by being easily found on the following list:
And this should be sufficient for wide public disclosure of a non-exclusionary form. This is similar to the EDGAR list that serves the SEC filings. IMO
