Sidebars vs. Widgets
The direction Wordpress design is heading will have (in my opinion) only 1 sidebar/widget-area for each 'physical location' on the page for the entire site. So instead of having 50 different right sidebars there will be only one right sidebar shared among all posts/pages/archives. Within that single sidebar, there will be multiple instances of widgets , assigned to be displayed when certain conditional statements are met. ( http://codex.wordpress.org/Conditional_Tags#Conditional_Tags_Index )
The deficiency of the 'custom sidebar/widget-area model' is already becoming a noticeable problem. It's redundant, static and not scalable. By its very definition, the only condition that triggers a sidebar or a widget-area is the type of page the end user is visiting. right-sidebar-portfolio-item and right-sidebar-blog-post only allow the developer to decide what sidebar (already prepacked with widgets) to display on what particular page.
Though at first glance that may seem dynamic, further examination reveals that the model is more on the static side. Its very likely that the two sidebars share at least one widget, that is needlessly repeated over and over again for every new sidebar. This goes against DRY design.
Factors such as whether to show the user the same or a different widget when the condition is true for: visitor is logged in/or not, visitor is from Malaysia, show one widget if its after 8pm in Malaysia and another if after 8am, if visitor's shopping cart has specific items in it... Such robust functionality is possible without redundancy when conditional statements determine which widget to display and not which sidebar to display.
All this is already possible now with Widget Logic (or competitor plugin). So a sidebar shared between multiple pages in a single site can (a) be overridden with a custom sidebar/widget area via a plugin or custom code (the past) or the widgets themselves can become dynamic based on conditional statements (the future). So when you see a sidebar shared among multiple page types, you are looking towards the future! :)
Thanks,
