This is a fantastic little app and kudos to the dev for getting out there and solving a problem with an elegant, functional solution then offering it to the world for nothing. Okay, so it only works with JPEGs but hey, 95% of the shots heading for FB are personal snapshots anyway and anybody who shoots RAW for that purpose is wasting their time and disk space. The vast majority of users will have no problem with this app and it's a hell of a lot more reliable than the web-based FB upload process, which seems to stall if you give it more than 5 photos at a time. Anybody who wants a pro-standard FB uploader with bells and whistles, Adobe have just put out an SDK for Lightroom plugins, you go write one and let me know who to pay.
