Is it normal to use
*techs.info instead of
*tech.info in a domain name? Is this correct, or can I not reduce "technology" to "techs"?
Technology in its singular form cannot be abbreviated to techs. But if there are clearly more than one technology in use, techs would certainly be OK. Yet most would use or understand techs as an abbreviation of technicians.
An alternative would be to abbreviate technology with tex.
