This tool is great for finding and curating content to share (though the topics selection needs a bit of refining), and for Twitter follower management. However, the scheduling function needs work. Scheduled posts often only show a shortened URL, so you can't see what it is without clicking through to it. And they are only shown in a list - a calendar view would be much more helpful. No way to set posting times, or add comments to posts at the time of sharing (only if you go back and edit it from the Scheduled list).
I think this may grow into a really good tool, but I think it's got a little work to do first, particularly on the scheduling portion. The curation section is pretty great, though and I expect that will save me a lot of time looking for content to share.
