Is a piece of content posted online a "post" or a "publication"?

I am working on an app and I was wondering which is the most correct way to refer to a user-submitted piece of content (e.g. a "tweet" on Twitter). Is it better to refer to it as a "post" or a "publication"? And why?

Additional question, if that piece of content is tied to a geographical location (e.g. submitting content on a public map), is there a different / better way to refer to it?

Thank you.

Solution 1:

A 'post' would usually be an item of content submitted to a blog or social media timeline, archived by date and time, so it's the right generic word for tweets.

If content is tied to a single location, it would often be a 'point', but there are other context-specific words, such as a 'node' for an object added within the structure of a digital map itself.

More generic terms for content that has been submitted include 'submission' and 'entry'.

A 'publication' would normally be a greater set of data than a single user submission, such as a complete magazine, journal, book or manual.
