How to come up with names and nicknames?
The first problem, with my own nickname - has already grown to a sufficient level and I think that we should participate more actively in communities. And for this you need to come up with a single nickname under which to answer in order to start being remembered by people. Looking at prominent people - both nicknames and accounts in social networks, domains are the same, but no matter what I come up with - domains and nicknames on the main sites are already taken.
Well, as the main question - how to come up with the names of services? It is also quite difficult to find something harmonious with a free domain and accounts.

Answer 1

People create "nicknames" from their relationships with people, and the naming of services -
other
principles

Answer 2

If there is some ordinary, popular nickname that is on every forum, try to translate it into a non-Indo-European language: Hungarian, Finnish, Turkish, Albanian (suddenly!).
The names of sites and services are thought out according to the meaning. Everything is complicated here and there are no general tips. Some big money pay for good names. If there is no money, a suitable name is invented for at least a year, while the code is being written and the purpose of the project is being rethought.
