 Hello to you all from Marburg University. Two years ago, we started this video channel not knowing how popular the channel and our videos would become. Until today, we have gathered about 1.1 million views. We've almost got 11,000 subscribers. We've been blessed with nearly 2,000 comments, most of them positive, and we've been enjoying 7,000 likes. At the same time, we have been given exactly 100 dislikes. Of course we could say, does that matter at all? It's less than 0.01% of all views, and by the way, it's the same percentage of negative views Michael Jackson received for his famous video, Billie Jean, of course on the basis of 120 million views. So nevertheless, we could simply say, so what? Whatever you do, you will never get only positive reactions. Whether you're Michael Jackson or not, whether you're the present king of France, you know who he is? Well, he's bald, as far as I remember, but that's a semantic problem. Or whether you're the virtual linguistics campus. So we could simply leave it with that. However, we do care. More channel is not made for entertainment, but it's a scientific channel. It's all about linguistics and web technology, with a few additions of my just wrote Tal Song interpretations. In fact, I received two dislikes for my four songs, the usual 0.01%. But in a scientific channel, it's not about taste, but about scientific adequacy. We want to be up to date. We want to adhere to the state of the arts, and our main goal is scientific accuracy. So the dislikes mean a lot to us. If they were just a matter of taste, they could mean that people do not like the way I look, the way I talk, how I'm dressed, that they do not like the way I write or integrate pictures in my presentations, or that they simply do not like the way we present linguistic information, and so on. In the worst case, however, the dislikes could mean that we are scientifically inaccurate. In fact, in our 300 videos, there are passages where you could argue about the content. Take the discussion of proto-languages in the video from Indo-European to Old English, or look at the debate about the evolution of human language, and so on. In these videos, you helped us a lot. And the comments that you posted raised some interesting points. They were useful and highly important for the assurance of the quality of our videos. But of course, we made mistakes. Here are some of them. I put Shakespeare's death to 1618 instead of 1616. I had Jackson Town in Missouri and not in Mississippi, and I said that in labial, dental consonants, the lower teeth and not the lower lip are involved. Such comments that draw our attention to wrong facts are corrected as quickly as possible. We do not upload the video again, but we normally add annotations or call-outs in order to implement the corrections. But what can we do with the uncommented dislikes? Well, of course, we could use our channel statistics. If a video has several thousand clicks and just one dislike, there is no need to bother. If, however, the percentage of dislikes is about 1% or even higher, I would say we do have to bother and think about redoing the video. Fortunately, that's not the case in our channel. Another option might be the geographical source of the dislikes. If they all come from one country, we may be confronted with cultural factors such as politeness effects or with different ideas about presenting linguistic facts. If the dislikes, however, are evenly spread around the globe, as in our case, there's no need to worry. So what can we do with the uncommented dislikes? My personal opinion is nothing. As long as those who press the dislike button in YouTube do not couple their bad mark with a comment. So my appeal to all of you is if you find a mistake or if you want us to improve a video, let us know. But do not just press the dislike button without justifying your judgment. OK, so much for now. I must admit that I do not appreciate dislikes at all. Every like, every subscription, every click are wonderful motivations for us to continue. And every dislike is somehow a slap in the face. And we ask ourselves, what have we done wrong? So please, if you want to express your disapproval, write a constructive comment rather than simply pressing the dislike button. So thanks for attending this slightly different presentation. The next one will be about linguistics proper again. Until then, thanks for your attendance.
