Yes, you can limit the website you own to a certain number of youtube videos.
The current video length limit is 15 minutes Only YouTube partners can exceed that limit
If you comment on a video it gives you 500 characters, so yes there is a limit.
There is no limit to the amount of videos that a user can upload to YouTube. There is a limit of fifteen minutes for each video, but this limit may be lifted on application to the site, and there is no payment required for this.
The time limit for a normal user is 10 minutes. If you have a partnership/partner account, it can be over 10 minutes.
Various versions of the song "No Limit" can be found on YouTube, including versions with lyrics, featuring video posters, and the official video. One can also find videos on Daily Motion and last.fm.
The 10 minute limit YouTube places on its users is because before this limit was in place, users were able to upload unauthorised content - such as whole movies - which went against the sites terms and conditions. However, it is possible to upload longer videos if you are a YouTube partner.
