In the last couple of months, I've had a couple of people try to bring up other TLDs during negotiations. One was for .blog another was .io I find these so easy to rebuttal that I now almost welcome these "gTLD" objections. It opens a door for me to better elaborate on the value of my domain. For the .io guy, who told me he can get the same name on .io for $30, I sent him a link to the sale of Agario.com, a domain that once had next to no liquid value or type-ins, now gets a ton of free traffic, and sold for $10K in an auction simply because of the popularity of Agar.io. I sincerely wished him the best of luck with the popularity of new project using .io. In response he increased his offer substantially than his initial lowball (which was still less than what I would consider, he was a small-time app developer and just didn't have the budget). Till this day, the .io version of my domain remains unregistered. He probably opted for another .com within his budget. For the .blog guy, I replied the same, but this time also referred him to Twitch.com which was acquired by Amazon after acquiring Twitch.tv, and also educated him on the fact that there was no way that the keyword.blog equivalent of my domain was going to be available for a standard regfee (it's a 3-letter 1-word), it'll be either taken by another investor or have a premium renewal, not to mention increase the value of my domain should his blog become a success. They emailed me a week later with a higher offer, again one I don't care to accept. So just a word of advice when negotiating, gTLDs make your domains more valuable folks, not less. People just have budgets to work with and have new options to settle for, and for those who settle and find a gtld will help them be looked at as "innovators" and will "stand out" - Go right ahead, you're driving up traffic and demand for a keyword or phrase available on thousands of other extensions, including the .com that is sitting there getting more traffic than it originally did, waiting to be purchased, likely by another innovator with a bigger budget.
