This is my current favorite app for sharing lists of links. I don't know why's it's so hard to find an app for this purpose that is well-designed and has good mobile apps. My only problem is with the firefox extension. Sometimes the "drag to dropmark" icon will show up on the right side of a webpage when I wasn't trying to drag anything... and it doesn't always go away. Sometimes I have to reload the page to get it to go away. Also - and I know this is something that's not so easy to accomplish - the website screenshots are not always what I'd want them to be. Certain sites have a main product image for that page and sometimes Dropmark just uses a page screenshot. I'm sure they'll get that down in time! Thanks for your hard work!
