The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About <view-source>

View source code of online HTML, CSS & JavaScript files. The extension automatically downloads the source locally and opens the file in a rich code editor with syntax highlighting support, text search, code collapse and more. If input is in the following format: protocol://domain/file_path:row:column it will automatically set the cursor in that position, a productivity booster when it comes to debugging.
