jQuery has simply won the Javascript framework marketplace in dramatic and dominating fashion. I don't remember the numbers, but some really high percentage of web sites now use it. Mootools, Dojo, and all other competitors are more on the fringe every month. People with all of the arcane knowledge needed to make complex DOM manipulation work perfectly across all browsers (including IE6) were rare to begin with, and now with jQuery at the level of maturity and support it has, and with performance issues improving, it seems almost silly for anyone aquire this knowledge and attempt to use pure JavaScript alone (especially since it's a highly flawed language to begin with.)
