Adam,
It is feels like an avalanche of gTLDs looking through this list. So many extensions.
I haven't invested in any gTLDs yet. I think some are useful for company branding, for local use, or for developing sites tightly related to the extension.
But I'm unsure about the investing opportunity, especially with the best names often held back.
I still would rather invest in .com.
It's really difficult to predict which will survive and possibly become ubiquitous and which will fail.
It wouldn't surprise me that a good portion are total busts or just are not viable.
The sheer amount of extensions is also a challenge to their viability vs a .co release which was heavily promoted and didn't have to compete with a myriad of other extensions.
What are your thoughts Adam? Have you invested in any gTLDs so far?
