'HowTo's (HowTos, HowTo's, or whatever you prefer to call them) are excellent problems solvers: they provide quick, easy-to-follow and non-overwhelming solutions to one or another problem that pop-up during daily routines. People love them, especially when they're free, regardless whether it's a step-by-step guide or a couple of minutes long video.
Good news, the amount of freely available, user-contributed HowTo's out there is staggering. There is something for everyone: ranging from fun stuff i.e. how to make invisible book shelf, imitate gunshot wounds and even open up a Coke machine to more practical stuff i.e. how to negotiate a raise or tie a Tie. All categorized, commented and rated by users like you and me. Below you'll find all 'HowTo' services we could find, as always all free, well-categorized and hopefully objectively ranked. Plus a bonus 'HowTo' search engine at the end. Enjoy!

Google Coop - 'HowTo & DIY' Search: Here is something worth a bookmark, to make things easier I created all-in-one 'HowTo and DIY (Do It Yourself)' search engine, using Google Co-op. This custom Google-powered search engine will search on all of the above mentioned 'HowTo' sites, simultaneously. Works great,... TESTed.
