[Mini-WWW]

As far as I remember, the Instapaper simply saves web pages for reading later. Although it may somehow facilitate easy reading of long text content (e.g., by moving it into another reading platform like Kindle), but not too much.

When you click on a "Text" button in Instapaper you get a simple uncluttered textual representation of the page.

Unlike Mini-WWW, the problem with Instapaper is the resulting format is the SAME for all pages! It's rather boring world!
