My thoughts about mediastorages

Mail.ru video

Very inconvenient for downloading, a lot of ads. When downloading, it installs many unnecessary applications, changes the main browser. Can block for no reason, very inconvenient to use. Not optimized at all, it works slowly and poorly. Freezes, can be thrown out in the middle of work. But there are many different materials that can be brought to another platform.

Slideshare

Very user-friendly site design, many presentations in different languages. You can easily bring your presentation to another site. Very simple and fast tag search. Your own presentations are also very easy to download and then edit. But you cannot choose the presentation language, which complicates the task.

Youtube

A very user-friendly interface that is constantly being updated. Videos can be added to favorites and then revised, there is a search history. All videos are categorized by tags, which makes searching very easy. There is a children's mode. Very strict moderation, every complaint is checked. It is very easy to display the video on another site, or just copy the link to it. Videos load quickly and without complications.
