The more I look at this situation the more I see that motivating on a translation of some topics usually doesn't lead to what is expected. Right, there appears some translated text, but if a translator is not really interested in what he translated, then he doesn't support the topic, has nothing to unswer on appearing questions, etc. And the topic goes down, meating with very few interest and only on the start.

For a topic to be active it should be kept up. So the OP should be interested in what he writes (or translates). Even if some topic is really infortmative but is not kept up, it will be forgotten really soon.

The positive result of any topic including the translated one is when it is talked for weeks, months and even years. And not when it was only translated once and forgotten right after that.
