A flashy self promoting main page is fine with me, it is quite appropriate to include "reasons to use sme" on the main page, go for it, you have the wiki sandboxes, you have bugzilla.
As I understand it, smeserver.org was an attempt to have a website promoting sme, but was discontinued due to lack of maintainers. smeserver.org currently resolves to the main contribs.org wiki site.
I gather there was also an idea to have a commercial section on the smeserver.org site, where support personnel could advertise etc, but such ideas never developed as there were no creators and maintainers volunteering.
I think this whole topic is also related to the elections issue and previous attempts to have a formal management structure in place, please see the forum about "elections etc".
SME could do with a Promtions Manager etc to push such things as creating a bigger public profile for SME. It can all be done, it just needs people to step forward and actually do it, rather than suggest what should be done.
