Sense: noun/1
For noun sense 1, posting and post both mean writing put online for others to read, but post is much more common in everyday use. Posting can sound slightly more formal or technical, especially in older internet contexts. A comment is usually shorter and reacts to another person's text rather than starting the main topic. An entry often refers to a blog item, diary-style record, or listed record on a site. An article is more planned, edited, and information-heavy than a normal posting. Use posting when the focus is simply on something published online: Her posting got many replies. Use comment for a response underneath it: I left a comment under her posting.
Etymology
Posting is built from the verb post plus the noun-forming ending -ing. In sense 1, it grew from the idea of assigning someone to a post or place of duty. In sense 2, it comes from the older verb post meaning to put a notice where people can see it; later, the same idea was applied to putting writing online for public view. Both lines go back through French to Latin roots connected with placing something in position.
