Is WordPress the right platform for our new Faculty Commons website?

Requirements:

The Faculty Commons online presence will be a compendium of resources from the units above.  It will deliver self-service and staff-assisted help, best practices from UD and elsewhere, collected calendars, training sessions, and funding opportunities, all within an online environment conducive to community building among faculty.

By the numbers:

• self-service help: How is this going to be organized? Are these posts? Pages? Links?
• staff-assisted help – maybe this is just a contact-us page? How can we prevent requests that should really go through Footprints? Maybe ALL requests should go through Footprints?
• best practices – again, are these to be blog posts? How will they be organized, searched, etc. Who gets to create them? Who vets them? Who certifies them as “best”?
• collected calendars – Google calendar embeds?
• training sessions – what is the relationship with existing /learn sessions?
• funding opportunities – formidable forms? Google forms?
• community building – I see that there is a Communities tool here, but I don’t see any of the elements appearing in the site. How do I link a user through to any of the Community tools?
• Try this link

I don’t see any requirements that can’t be dealt with in WordPress, except for the most important one: community building. How do we motivate people to visit our blog, let alone post to it, or subscribe to it?
