I would continue using Shovel for now. It is a disappointing first version for a number of reasons. You can't comment, in app browser is sluggish and crash prone, you have to log in via the in app browser, hyperlinks in comments are not active, no landscape and no Instapaper support. I like the search though and the ui is better than Shovel. Just not good enough to get me to switch. It does however have potential which is good.
