Allow me to start this discussion off by saying that though the requirements of this site are a bit relaxed, there are still some rules that posters need to follow. New users tend to post low-quality questions and answers on this site, often because they don't know the site rules outlined at How to ask and answer software recommendation questions - aka 'The Ground Rules'.
On Stack Overflow, new users are forced to see a help page and must "agree" to follow the rules of the site in order to get to the form. This requirement is also there on Server Fault, Ask Ubuntu, and Math.SE, but no such requirement exists on other Stack Exchange sites, AFAIK.
My proposal is to require new (< 10 rep) and unregistered users to see the interstitial page and to "agree" to the site rules before attempting to post, like Stack Overflow is doing. This will help curb low-quality and off-topic questions from new users by forcing them to at least glance at the help page.
You may be asking "what if the user just clicks through?". This problem can be solved, I think, by forcing the user to have to wait 30 seconds before he/she can click onward. However, some may argue that a wait is unnecessary.
Yes, I know that the advice page is a little generic now, but I think that it would be more effective if it contains what is in this answer. In fact, people who share links to this site are encouraged to link to that answer instead of the homepage. Enabling the interstitial would make sure it is seen by all new users, not just those who arrived at the site through that answer.
