"Long Page Applications" (vs. Ajax)

Question

I'm considering doing all my new websites in Flex, however I have one concern: Many website pages' content go way down pass "the fold" and are very long (or high), as you scroll down and down using the browser.  (e.g., a forum thread with many posts going down the page)
Flex (on the web) seems more of a "above the fold" paradigm.
Here is the question: is there anything stopping a Flex application from being very tall (like 3-5 pages high)?  Does it work just as well?  Does Flex handle that well? Is there a limit to how tall/long a Flex application can be?  Would Ajax be a better fit for tall website pages?
In other words, would it be technically possible to translate/re-write most websites in Flex? or is Flex not really design for tall sites?
I hope this makes sense.

Flex is not incredibly good at dealing with large amounts of text, particularly if that text needs to be formatted.
htmlText property and Flex support for HTML tags and CSS are just too limiting for many applications.
That said, in many cases Flex might be a good solution. For your forum posts example, the posts could be rendered using a List or Repeater.
