is there anyway to implement stackoverflow-like style or functions in xoops?

I was wondering if there's a way to hack CBB or other modules to mimic the stackoverflow-like functions: people could vote for each answer/thread & most voted answer (thread) would rise to the top.. etc.

I don't know about any hack but you can use a service like ogr3.com

This is how it works:
1 - create a link in your cbb post template to ogr3.com/yourtaghere, you can use your site name has the tag, tag only allows 33 characteres and a-z A-Z 1-9 and _
2 - Give a descriptive name to that link like: VOTE UP
3 - When someone clicks on the voteup link it will insert a record of that entry on ogr3.com/yourtaghere
4 - Ogr3 will display the top pages on the last 3 minutes, 3 hours and 3 days.
5 - Ogr3 has rss feed for each tag, you can use an rss reader module to grab the top threads of your tag and display it on a block, this way users do not have to visit ogr3 to see the top threads.
6 - Be aware that other sites may share the same tag, and results for other sites are counted. Choose a unique tag and you should be fine.

Look at this example http://ogr3.com/xoops

Once you click this link you should see this very page in the top list along with other xoops related news

thanks Trabis! the ogr3.com seems really promising!

however, what i'm looking for is a way to reshape the forum on my website to make it easier to use.

nowadays, it seems there's a trend that the stackoverflow-style question/answer systems gradually replace the functionality of forum. So i think maybe it's a good idea to implement stackoverflow style and functions in xoops.

after searching google for a while, i've found several examples of implementing stackoverflow in drupal:

and some guy even started an open stackoverflow project:
