Used to have an account on that site and have (or had while I participated a few years ago) a forum site much like here. Was poorly moderated and several were posting dreadful information about food safety/nutrition/etc. so I just stopped participating. I never save recipes on any website. You have no idea if one day that site might vanish and all of your recipes would also be gone. If the internet happens to be down the day our plan to do a lot of baking you could also be out of luck. Allrecipes was created by combining many older sites together. Some of those allowed direct posting of recipes, many of which turn out to have errors in ingredients/quantities/instructions. Their current website has no test kitchen, so even newly 'approved' recipes simply go through an editorial process prior to posting. I have found so many other good recipe websites who have test kitchens that actually make the product and perfect the recipe before posting them, I just stopped using Allrecipes.
I also avoid recipes from some random blog person when doing a search. You have no idea if the recipe is going to work and amateur home cooks often leave out things assuming you already know how something needs to be done.
I do a copy/paste of any recipe I like to a folder on my PC, so regardless of what site they are from, I have them all in one place. I can also easily make modifications to the recipe/instructions/etc. and don't have to worry about some site suddenly disappearing.
