One wonders why the "drink from the firehose" style reader (Reeder) hasn't been merged with the "save for later" style reader (Instapaper). Everyone I know who finds one of those indispensable becomes enamored with the other pretty easily.
My regular flow is to have everything (RSS for blogs with long posts and RSS for simple alert/notification blogs) in Google Reader and filter through it there, only viewing everything once. Anything longer than a paragraph in there goes to Instapaper, to really read later.
I sent random links and website I want to save to Instapaper as well and was moving them to Pinboard manually on the website, but this will definitely save me time.
