Although I don't find much use for most of the goodies that Giveaway of the Day provides, I like going through the candid comments that the site's loyal & informed users share. The technical discussions about the products are interesting as some folks in that community compare it with other available alternatives including freeware.
From such discussions, I've been able to learn about startling & trivial facts about PC utilities. For instance, I got to know that that there are tools to unlock restricted PDF documents & recover passwords of protected PDF files, EXIF cleaners to remove EXIF data from digital photos (EXIF stands for “Exchangeable Image File Format”, practically all digital photo cameras include additional information (metadata) with pictures or audio captured with the camera) - information that is otherwise not easy to find if not for this kind of forum.
