The first time I went to Ebay, it was in search of a record I'd had
as a child called "The Wobblin' Goblin".  I tried to register with
the username "wobblin" but, to my surprise, it was (or was said
to be) taken.

For some reason it then occurred to me to add an 'i', and register
as wobblini.  Since that time, I've used wobblini as a server name
and as a username on other sites.  I'm not very into the nick and
alias culture, but when you have a name that's as common as mine
is, especially when you try to make a nick like "dblack" or "davidb"
out of it, having a coined name available makes things easier.
