Adobe
This information is very current Adobe updates their information with every new software that they release. Like when they go from 2023 to 2024 software, they will update the information accordingly. Adobe is the company posting the information they are the most knowledgeable on their software because they create it. If any site is going to have the most accurate information about Adobe software, it will be Adobe themselves. The posts are made by Adobe there are no gatekeeping mechanisms in place. People who work for Adobe are the only ones posting these tutorials. I would say that most of what Abode posts are easy to follow and are clear. However, I have had trouble following some of the tutorials they post because at some points they are not as descripted or use the best pictures. I would use them in the future because they are almost always reliable.

YouTube
YouTube has a lot of current information as well as a lot of outdated information as long as you are on the lookout you can find information that works for you. I have found some information that is older that is still relevant and information that is older that is no longer relevant. You can also find new information it just depends on what you are looking for. Some people are authorities on YouTube, but that is another thing that you have to look out for on YouTube. I think the most effective way to tell if someone is an authority is the quality of the content. I have found that the better quality the content the better the information is. The way that content is presented to you by YouTube is through an algorithm. It bases the information that it delivers to you based on what you have looked at and searched for in the past. The content is clear sometimes and sometimes not. I have watched tutorials that have no audio and they run through the tutorial, and you have to figure out what is going on for yourself. Other tutorials are full information with no questions needing to be asked. I think again it just depends on the content. I will use this in the future with the knowledge I have, knowing that sometimes the content is not great.

Everything that I found from was from 2023 so you know that all of the content is fairly new. The posts are made by qualified contributors hired by Evanto TUTS+. All of the information was accurate and well detailed that I saw. I think things that are posted on the front page are all things that have been voted on. At the end of each article there is a little vote thing that says was this information helpful. So, I think that the website takes those votes and puts the stuff that is on the front page is stuff that other people have found helpful. The information that I had saw was accurate, well detailed, and easy to follow. I will definitely be using this information in the future. I wish I would have found this information earlier I feel like it would have been a great asset.
