News and Blogs are both very similar in nature - they are content curated for and interacted with by a certain audience.
However, they can suit various purposes, so here are the key differences:
1. Author
News is typically created and published by one person or a group of people who are authorised to know and cascade information about your Company or anything relevant to its operation.
e.g. A "Company News" channel which is typically authored and published by the Internal Communication team, or "Marketing News" which is managed by the Marketing Team.
A blog on the other hand is written by an individual (or group) who has expertise in a specific subject matter or covers a certain field.
e.g "CEO Blog", "Research Team Diary", "John's European Adventure"
2. Purpose
News has a clear purpose, and articles written are intended to share specific information with a wider audience.
A blog is usually more informal and can be an expression of random ideas or opinions on a subject.
3. Content
News is fact-based, formal, and well-structured, for example: "Company's Financial Goal Achieved"
A blog is less formal / more conversational, and it can contain someone's opinion and expression, for example: "Benefits of using Agile in our Organisation"
4. In Claromentis
News is likely to be used, and articles displayed more prominently due to the content matter it deals with, whereas a blog's nature lends it to be an option that may not suit certain companies' Intranets.
Subsequently, most Intranets can find a great use for a News channel, but not necessarily a Blog it really depends on your company and its needs!
