Thanks to the exposure gained here in IH, today.domains has now 5 subscribers!
There has being no further promotion, and I'm currently a bit hesitant about posting about the project in other channels, since I feel there's still some more adjustments that I need to make in the landing page and in the background technical setup before "opening the gates".
All in all, I'm surprised and proud of the positive feedback gathered and the (very small, but still) traction gained with so little promotion so far.
