You should write a blog article when:

• Your content is a formal corporate announcement, such as an organizational update or new corporate tools being announced (e.g. a new HRIS system or a new expense technology).
• The information must be presented in a specific format (using templates).
• The content you are posting is lengthy.
• The content is timely and will likely not have as much value weeks/months after it's posted. 

You should post a microblog when: 

• Your content is a quick update or announcement, such as promoting an event or congratulating a person on their work anniversary.
• The information posted will typically have no specific layout (ad-hoc), and GIFs are encouraged.
• The content you are posting is succinct.
• The content is social in nature. 
• You believe your content is relevant “now”, but not in the long-term. (e.g. posting that donuts are in the shared kitchen is relevant now, and might not be relevant 1 hour from now, when the donuts are all gone).

You should write a wiki article when:

• Your content is "living" and it evolves on a regular basis (e.g. a how-to article gets updated whenever new features are developed and released).
• The content is a repository of information (e.g. a repository of customers, addresses, etc.).
• The content within it should be easily accessible for copy/pasting purposes (e.g. I should be able to easily copy/paste a biography).
• The content has long-term value. 

• You want to create a feedback mechanism, source ideas from your employees, or collect questions about a specific topic.
• You want to be able to track content that "resolves" a particular conversation.
• There is a conversation to be had between experts and the rest of your employees.
• There will be multiple submissions related to a single topic.

• Your content is short and acts as "to-do" content.
• Content is related to a specific action required.
• There are multiple smaller action items related to a larger task/action item.

You should upload a document when:

• Your content is a corporate template (e.g. a powerpoint template).
• The content is a recording, a video, an image, or a graphic.
• The information must be easily downloaded and shared with a third party (e.g. a user guide, a technical brochure).
• Your audience must be able to access the content using the Desktop Client Tool or the File Manager application. 

• There is a specific date and/or time associated with the event.
• You need to invite attendees to the event.
• You want to monitor the number of attendees and who they are.
• You want to remind attendees of a date/time.
• You are trying to create a well-defined schedule.
