I want to add to this, I just went on a youtube channel I like, and I scrolled through 86 videos not knowing which one I wanted to import, knowing they would take a while to upload and I wanted to make sure I chose the right one. If I didn’t have to wait, that’s 86 potential videos that I could have watched and kept engaged with LingQ.
Now I know, that’s something I can easily change by saying “let’s just pick anything and enjoy it”, but then the user is making a conscious effort to do that. Any time you introduce an additional step for your users, or another obstacle such as this, what happens is the pool of users who will actually go through that shrinks.
For lack of a better example, you can see this type of behaviour in video games where the achievements are visible to everyone. So you will see something like, 53% of people have completed the story, 70% of people have completed the half-way point of the story, and 92% have completed the first chapter.
The goal is always to keep your users as engaged and active with the site as possible. One of the key components to achieving that, is ease of use on your site. If you look at the cost of adding in the previous functionality as an additional option, versus the cost of people tiring of using the site due to the accessibility of the site and content, I think this is a definite win situation to add the option to “quick import” based on the existing auto-gen subtitles (on top of the option of the improved, but time-waited, method of subtitle imports) .
A simple implementation for the user on the front end (I know the backend there is work to do), at the time of import, if it’s an auto-gen-only youtube video, have a checkbox on using enhanced subtitles (or viceversa, all depends on which one you want to use as the default, and then the non-default one becomes the checkbox option).
I hope you take hopeful consideration and look at the benefits of adding this, not only for the users, but for the success it can maintain/enhance of the LingQ name going forward. It would certainly at the least stay level with any competitors who are out there doing a similar import-and-learn concept site.
