I’m not sure how long it’s been around (forever?) but it’s new to me: Instapaper. I have been wishing for this app for forever. My biggest online problem (aka first world online problem) has been not having a handy way to save online articles and posts to read later. I’ve tried starring things in reader (but these get mixed up with the things I simply like and want to return to later) and tagging things “to_read” in delicious (though I don’t think I’ve ever returned to delicious to read or to make or to buy; in fact, I barely use delicious.). I’m very happy to finally have a proper tool for this.
Plus bookmarklet. Basically, if you have a bookmarklet for your project then I think you are awesome.
