Im for lot less forums too:

-Rename "official apps" to "Nokia Applications"
-Rename the terrible "3rd party apps" to just "Applications"
(If u ask me I would move the 'Nokia Applications' as an Application's subforum and remove all the other application specific subforums)
-General (maybe a subforum for video links?)
-Offtopic
this IMO should be the core

No way a newbie can understant what is really newbie: I would suggest a 'rate' system for senior members and keep the threads togheter in the 'right' forum.

'Last post' on home page is 90% useless to me i would prefer the direct link to the thread that received more posts in last 12 hours.

Add an empty 5 star jpg to each thread: people just dont know that rating exist: to make someone vote for my thread I had to
downvote mine with a 2 just to put the stars there . A sad 1 star thread now is much more visible than a clever one with no stars...

I would promote the position of threads connected with a maemo project: if an application begin to be dowloaded from maemo make sense that the relative thread receive more 'visibility'.

Since Nokia was hiring maemo related people like crazy during last months seem a bit odd to me there isn't a 'Job' thread on ITT.

A bit offtopic note: garage should not let people uploads jpg and screenshots: I used (not in a malicious way) the garage repository and linked the screenshots on ITT and I probably generated a lot of waste bandwidth and + fake stats on the maemo charts: I just realized that watching one of my minor stupid project being on the 'Most Active This Week'. Just suggest people to use ano other 'pic site' and block the jpg upload on garage
