Well, that's all dandy if you don't like SE's hitting data... sure you can set a seperate "non frames" path for them, but most users neglect to... There are tons of other reasons not to use them as well:
1. SE's cannot read data in frames.
2. Users wanting to link back to data in a specific frame that they've navigated away from the index, will be linking back to the index vs the page they want to bookmark.
3. Scrollbars will look like crap inside of your posts...
All in all, not a valid trade in my book... more hassle than it's worth...
