Brian from Instapaper here. There seem to be a number of comments expressing concerns about the acquisition, and I wanted to just jump in and offer to answer any questions you have about the acquisition.
Based on the comments I've read below the main concerns seem to be that Instapaper will either be shutdown or materially changed in a way that effects the end-user experience. I can tell you that neither of those are the plan for the short-term or long-term of the product, and I am personally looking forward to providing you with the same great service under a new owner.
