Most of projects you implied are scam ones.
So, it is not strange to see people don't have too much interest in new ann topics.
Yeah ofc that should be done. But I have seen so many new anns of the same old coin .. and those new topics look like nobody is interested. And thus I am also not interested and close the topic aggain before looking deeper into the coin. There are so many projects.
For Snowgem, that is a real project, I don't think new ANN topic of Snowgem will fall into ignorance.

I would vote aggainst a new thread. You can also include the news into the first starting post. You are free to use as many space in this post as you want to. I don't think there are any forum limitations ...
