If I want to work on a web app with 2-3 months of timeframe in mind, which technology should I use? HTML5 + CSS3 or HTML4 + CSS2?
Few points I am considering
Compatibility of browsers
Ease of use (especially with IE)
Advantages over html4

Some of the APIs can be useful, but need to be taken on a case by case basis … and still function in HTML 4.01 documents.
Avoid CSS 2 in favour of CSS 2.1 (since it better reflects what browsers actually do). Examine CSS 3 properties and selectors on a case by case basis, comparing benefits, browser support, and what happens in the cases that browsers don't support them.
