Simply put, they are the most realistic option. For example, fsp.country is available, but at $4,000 per year which is way more than I care to spend on a domain with my limited funds. With that said, Kaldus.com is simply affordable. For the phone service site, fsp.phone is just not an option available for acquisition. I am guessing that is not a valid TLD.
Pilone.name is intended for the Pilone Family that is in good standing with me. Currently, there is only 1 active domain, and that is a memorial site for my brother. My website redirects to my personal domain. Options can include my brother’s children, but they never seemed interested in having a website, and I don’t know their Facebook address, or I would have set up redirects to their Facebook Page.
