Yes. This is one of the key reasons behind creating SO and why it worked so well at first.

As well as non-current content in some sources getting buried or otherwise being hard to find, or simply expiring (individual forums going offline), the other issue was the distribution of people willing+able to answer questions around the many disparate forums was inefficient – for all the talk of “the Internet should be as decentralised as possible” no one has found a better answer for this than a bit of centralisation with open licensing (SO wouldn't have attracted as many of the better people answering if their work was going to be locked in rather than covered by something like CC-BY-SA).

The solution that is taking over a bit ATM is Chatty Glorified Predictive Text and its friends, because this gets around the latency issues (you get a much faster answer, even if an incorrect one that means you need to rephrase the question several times) and licensing issues (though IMO the morality of that is rather dubious, the legality of it is still being argued in a number of places, but nether question of legality nor morality is going to stop it happening going forward).
