I will say that I do believe they will add core messaging and calendering features. The 2 things are all central to how we communicate (low hanging fruit), so I think it is safe to say they will eventually add this.

I think you have an interesting point with Linked In as well. Interesting concept for how they could bring value to their shareholders. I suspect they would not do this… but that would be pure speculation. Linked In is a great service, but they have an uphill battle against facebook and keeping users. They are smart guys; so it will be interesting to see how they rise to the competition. Glad to see that they FINALLY added photos.

Great post as usual.

What are your list of 6 missing core features that app developers should reserve for Facebook?

WRT LinkedIn, I think it is dead. We only need one Social Network and all the sub-groups in my life can be managed via the feature you describe. If I were Linked-In, I would try to cut a merger deal with Facebook where I bring them all of my users in exchange for x% of their company. This would give Facebook a quick bump in business-oriented users (e.g., a few million LinkedIn users) and it would give LinkedIn shareholders a much more valuable currency than they have right now. LinkedIn should act quickly because their install base is a wasting asset. The one other play they have is to sell their business to Google so that this card goes in the hands of someone who would like to own and control as much of the facebook install base as possible.

Thanks,
