Apple should just take the time to upgrade their services on their own. Purchasing Twitter would be a huge financial cost, and their users could at any moment flock to a competing service. Apple would undoubtedly make changes at Twitter if they acquired, making the "possible" exodus more likely (I'm not saying it will happen, just a possibility).
Apple has the cash to update their web service. Just hire some recruiters, pay more than than the competition, and get to work.
Not sure if they have the balls to let go of WebObjects though. It's their baby. Quicktime is another product that I feel Apple needs to let go of. Their supposed commitment to HTML5, yet the only site that streams video (movie trailers) requires their dumb plugin. Edited 2012-12-09 03:23 UTC
