The Contribs home page says exactly zero about why I'd want to use SME Server.
I have had another look at the main contribs.org home page here
http://wiki.contribs.org/Main_Pageand it appears to be quite comprehensive, as does the whole site.
Not everything can be fitted onto one page, so it is inevitable that a visitor will have to click on other links in order to read everything the site has to offer.
The main introductory text is pasted below and does refer to other links, which if read, have just about everything anyone knows about sme server. Any web site can always be designed differently in accordance with individual tastes or expectations etc, but as a collaborative effort the existing wiki is a pretty good effort that has been created by many people over a period of time, and as such is an ever changing or ever growing volume of work.
If you do not like what you see, or feel there is significant missing information, or poor layout and design, then get in and help to "fix" it. If you propose changes, then your ideas will need to be vetted by your peers, and this is done by submitting any specific proposals via the bugzilla, selecting the web site category for your posts.
Personally I see nothing seriously wrong with the wiki, and the other contribs.org websites. They are a complex set of sites with a lot of information, and as such need to be compartmentalised into different pages and main sections.
Any visitor will need to familiarize themselves and spend time clicking on the other links to get the whole picture. As mentioned already there is a whole page and specific link dedicated to the good points and reasons for using sme, ie About SME Server.
Here is the main page text, which seems straightforward and readily leads me to other information.
Welcome to the information and documentation wiki for SME Server
We're here to provide collaborative documentation of the SME Server project. SME Server is a leading distribution for small and medium enterprises. It stands apart from the competition by shipping with most common functionality preconfigured and features a number of popular additional enhancements in the form of downloadable 'contributions'. It is published under the GPL license and while freely available, a small donation is requested.
