How many times has a private beta piqued your curiosity? How many times has it turned you off because of the nature of it being “private?” What about both?
While the notion of an exclusive crowd joining a social networking site probably does frustrate you (as it did for me on many networks where it took a bit of time for me to score an invite), private betas are still very smart. The buzz surrounding the brand new piece of software is complete word of mouth marketing, and it works quite well in the favor of those who opt-in for such private tests.
Pownce is still in private beta. I compared Pownce to Twitter over a month ago, and people have consequently asked me to invite them (I still have some invites in case you’re wondering). Mashable was able to get a sneak peek of Notifir. I now want in. Donna Fontenot gave me a Grand Central invite last month. My good friend Muhammad Saleem is always giving away invites. And of course, there’s also InviteShare, which was recently acquired by TechCrunch.
