Why feel the need to call them dashboards, platforms, web apps?

They're websites

The majority of people I know think of websites as WordPress

Describing your work as such makes you sound more important.

@bahua It's not about importance. It is about the skill involved.

Web site - selling and marketing
Dashboard - convey information quickly with numbers, graphs, and/or glyphs
Platform - base to build something on
Web application - an application but instead of it being a compiled executable it runs off the local machine; the browser is the GUI or it could only API then it might function like CLI or C-style calls.

A website can be an app, a dashboard, whatever the website does for you.

Why call them websites when they are just a text document that does stuff?

I just ++ed this rant because of the tag.

@Santaclauze I ++ed your comment for the same reason .

Why use any tags?

Just use undefined.
