You are right, I have also seen projects where the developers kept talking everyday, nowhere to be found after the end of the ICO.
On the other hand there have been several occasions where there has been a lack of communication from the team, especially after the end of their token sale. That silence causes a lot of uncertainty and a bad morale. As a result the price of the tokens have sunk dramatically. And we still do not know the status of their business.
You can see the effect of too little communication even in this thread. I have been quite cynical because there have been no answers to the questions raised in here. Then mere hours before the end of the sale the team pops in to say the sale is extended. I was excited about Soma because of the national interest they received, but if that behavior reflects the company as a whole they will have to impress me a lot from now on to dispel my doubts.
I think nearly no one would say something about the extension if it would be announced in time and not just a few hourse before the sale would have normaly ended. But as Rigorous already stated, this feels like a lack of communication to the community.
I think it was a good decision, but I wished they would have talked about it before. I also maybe would have recommend that they would have postponed a second phase of ICO and not just extended the current phase.
Looks like the right decision to me. It's better to take enough time instead of rushing.
