You people need to make your announcements more visible in the different boards, especially the service announcement board. To be honest, I even thought you have no announcement around until I had to look it up from your profile.
You need to make full use of the bump feature now and then, and then maybe actively post some new updates in the thread.
You are right, they need to open a proper ANN thread about their services and then bump those threads via different updates or by sharing the stats or something relevant to those services. To be honest, we need more of such services where one can buy goods and services using crypto but most of us aren't aware of such existing platforms.
I think these platforms offer higher conversion rates, but when more of such services are available, the competition will be high, and then we can get better conversion rates from bitcoin to local currencies.
