Who @dan @god @dimimp

Who Hive account@dan Hive account@god Hive account@dimimp.

So far I am very curious about them.
Finally I searched on google about them.
I found a steemit founder named daniel runner.

And I am very curious about a very generous person.
He is Hive account@dimimp.
He is very helpful for the newly joined steemit. He helped us by delegating SP.

I am very curious because so far do not know what the original form of a @ dimimp.

Does Hive account@dimimp include the founder of steeemit?
