NewG investing is not for everyone. Besides waiting for profit, you get labeled by the .com maximalist's. The conversations over the years have been very heated. Unfortunately, many conversations have strayed far from professional discourse. As a result many invest in NewG's, but never speak publicly about it.
As far as that, if you really look at when those threads go off course, it's usually a few things. Many times it's when somebody starts off saying something about .com, that's just off. Like .com is going to fail, .commers are worried, that kind of stuff = off the track. Then you have those that invest like fancy.domains where it's more, I invest in these simply because I expect to get more than I paid for it. None of the extra nonsense. It's how I felt when I invested in .me. Not once did I say .me was going to topple .com or .commers are worried. It was simple. I pay x for a .me, I made many times over when selling. That's it.
Another place it goes off the tracks is when threads get started talking about sales. But they don't mention the sale price, don't even mention the name. If you start such threads, you're going to get questions, because it's very easy to post stuff that's not true. Threads like that, invite questions.
Or something you just posted:
"My best domain, purchased off the collision list, gets offers that will hit the record books when/if I sell."
Record books? I don't remember the highest new gtld sale but I remember some $500,000+ right. So you're saying you're getting those type of offers and just not selling? I'm just not buying that. Those type of posts come off as fluffing, hyping the market up. If you're getting half million offers on your new gtlds, take them.
As far as talking publicly about new gtlds, many do. They're honest about it. There was also a forum dedicted to it, basically all new gtlders, it folded.
