Is this a good way to use the Google Sitemaps program?

hi i have just reviewed google's sitemap thingie.

this is what i have done:

1. create a script .asp or .php or something like that which genereates html output with the 50000 latest url's (50000 is the limit according to google's faq about sitmaps).
2. i have a site with user generated contents which each have an id so each line of the output has http://example.com/<<id>>
3. this means that google should find the 50000 latest urls each time it asks.
4. will google give up if it takes too long to generate? it takes maybe 20-30 seconds when i try it.
5. is this a good way to use sitemaps? i think i have got it but what do you say?

will this have any impact on my crawling? i have links to all these pages (they link to "previous" and "next" in a "linked list") so they shoulde eventllay be found by google i think

maybe this will speed it up who knows?

what do You say?

is it good or is it bad.

Why don't you make the same script save the output in a text file, then google can read that text file whenever it needs.

You can run that php script using cron. I believe that would be the best way IMO.

Only Google knows. Google employee Matt Cutts implies "no" in his blog. My experiments so far indicate "no".

Someday, I expect the answer will be "yes". I see no reason to believe that day has come yet, though.
