Tax deal apologist that I am, it behooves me to offer some constructive criticism, too, along with a reminder that this deal isn't final until the legislative process makes it so: Congressional Democrats, unable to unify around an original proposal, may try and adapt this framework. Here are a few changes they want:

"By a vote of 53 to 36, the Senate defeated a proposal to extend tax cuts first on those earning up to $250,000 in income," Capitol Hill's Roll Call explained over the weekend. It was a typical Senate defeat, where a majority supported the losing measure and a minority achieved a filibustered veto.

It's been well observed in Washington that it doesn't cost much to filibuster: Senators don't have to speak or stay on the floor of the Senate. They only need to say a few words to their leaders, and the whole institution grinds to a halt. The public, of course, doesn't see that level of detail, which makes things difficult for those interested in reform -- but that could change.
