I’ve set up an account at
Wists (via). 
The entry at Many-to-Many likens Wists to del.icio.us, but the distinction
between Wists (image/link bookmarks) and del.icio.us (site/link bookmarks) gives
me an early impression that Wists is an exciting addition to the tagged, social
and RSS subsrcibe-able systems.  Sure, there are correspondences, but in
short, it’s different enough that I can think of ways to put it to good use. 
The bookmarklet works well to parse images from text; early tinkering around
with it tells me so, anyway.
