I've found very few(if any) solid extensions where the LLLs weren't valuable too. .in is currently on the upswing, and as its popularity increases, LLL.ins will also increase in value. Not all LLL.in are worth alot, BUT, there is opportunity to make some nice $$ because:
1. cost of entry is low(few drops are going to be worth reg fee in a year or 2, they will be worth more)
2.The opportunity for growth is high,
so, this is one of the best opportunities IMO for a buy low, possibly sell high in the domaining industry.
