I found the main discussion threads on the /r/movies surbeddit the easiest way of finding if there's a post credit scene. The info is in the original post, so there's no need to read comments with potential spoilers.

http://aftercredits.com is a pretty good source as well, but I checked it out after your comment and surprisingly it doesn't show in the top search results for "<movie> post credit scene".

More and more of my google searches are being appended by "reddit". Someone's asked it before and it takes half a second to load/skip for it. It's sad, but effective

Pretty much all of my searches have that operator now. You used to type your keywords and relevant forums would come up on page 1, brimming with information from people who were knowledgable and eager to share what they know. I have no idea what these niche forums are going to be called, so I have to defer to reddit for my searches.

The reddit keyword is very useful, and so is just "forum". That keyword tends to pop up on forums, so it's useful for finding those niche forums.

Damn I guess this is true about a lot of other very specific questions but are not too niche stuff as well (i.e. programming questions). An example is I was searching if a game had local multiplayer, and what would you know the result was exactly what you described - a paragraph long description of the game and the advantages of multiplayer and the answer hidden in it.

This reminds me of people telling their whole life story and how that rice pudding made them a better person when all I was looking for was the recipe.

There's a chrome extension that surfaces the recipe immediately the page loads so you don't have to wade through a thousand pictures, pre-loaded videos and useless content https://chrome.google.com/webstore/detail/recipe-filter/ahlc...

same for "name-of-movie streaming release date" will give you a lot of seo filled long articles that often just end with "we don't know"
