They need to be either very catchy, if you are looking for brandables, either to have some companies using that word in their naming, if you are looking for exact match, either to find some companies that are using, exact match- the keyword+extension, if you are looking at ngtlds( as in 'Online Learning Today', there are at least a couple of companies named this way?) To make a comparison, I'm not saying that mine's are the best one's, but at least they follow some rules...these are some of the handregs made by me in the last couple of days: TransRise in .com( there are at least a few companies using this name: two in US, one in Houston and one in San Jose, one company in India, Mumbay, one in UK and one in Russia, there could be others to, but if you have at least a few end users, it should be enough), Pleasantful in .com( real word or a word resembling to a real word, ending in 'ful' and a positive meaning) RegalityHealth in .com( the health sector is very trendy right now, regality is a positive word, which works with 'health') Again, they are not perfect, it's hard to find the perfect handreg these days, but they should do ok.
