Drupal is an open-source Content Management System (CMS), which is particularly suited to customization through use of blocks, themes and modules. Drupal's innovative use of taxonomy and its unique menu system allow for effective management of content as a site grows or evolves.

Problem:

You have a "master" database that contains data from multiple Drupal sites and you want to share it among them. Normally, you could use table prefixing to allow each of your sites to point to a single table. But what if you do not want content from one site to "bleed" across to the other sites? Let's say you have a network of Drupal sites sharing a user database. You want to share that user's information across your entire network of sites, but only make the information visible from those sites to which the user has subscribed. Or maybe you want to populate baz.com with users who meet some arbitrary criteria. There are lots of possibilities here, but nobody's paying me to write this, so let's get on with it.

I think simple, clear site navigation is important. I've always liked tabbed navigation. But these days it seems folks want to use a lot of fancy javascript and images only to produce navigation tabs that are full of eye candy, but also not very flexible. This is where "sliding doors" comes in.
