Jeff: I found your follow-up comment regarding the different personas we all portray in life (employee, spouse, parent, buddy, etc.) to be very interesting. Mixing them on-line could prove to be very tricky.

Much has been said about the problems some young people are now experiencing as they enter the workforce, and find that their prospective employers are scanning their fun-loving facebook pages. Hard to be the life of the party and a promising corporate up-and-comer at the same time.

Perhaps projectstars can find a niche somewhere inbetween the pure social sites and straight business focused ones such as linkedin.

If you think about social sites at home, and business sites at work, maybe projectstars and others can become the “third space” sites where people go to socialize a bit while they also do a little business — like a virtual coffee shop.

As everyone becomes more time-starved, and keeping up with multiple social networks becomes a chore, these “third space” sites may just be the first place members stop.

I agree that the promise of OpenSocial is huge, and it solves a big problem. I haven’t visited my Facebook profile for two days, and my LinkedIn profile for three. Others have languished even longer. It would be terrific to have a way to multitask with several communities at once.

With the physical space, we have one persona when we kiss our spouse or significant other goodbye in the morning, another when we arrive at the office, and a third when we stop to have a beer with a first after work. Shifting becomes easy because the context-shift is dramatic: The front door versus the office building versus the neighborhood tavern. The challenge of OpenSocial or other persona-mixing applications will be keeping them straight, so we don’t swear in front of our boss or look too buttoned-up in front of our old college buddies.

Much will be required in our brains, not within the soft. I predict OpenSocial (or whatever it spawns) will be embraced by those still in school. The leap for those of older generations will be too great.

That’s one that always bothers me about social networks. It’s a chore for me to be posting things on myspace, facebook, and etc as well as my own blog. I do like the idea of open social, if I can just add social network elements to my own blog, that would be sweet. Though in a way the blogroll and etc is already a form of a social network.
