Depends which version and which font
What I was trying to do, was reference the Evernote logo, without trying to copy it, but still making the J of Joplin clearly evident.
Whether you appreciate the Evernote link or not, that’s probably why the majority of us are here, and regardless of this, the link with an elephant and remembering is still relevant.
Icons which are just simple letters don’t work well or look good, and aren’t meaningful or memorable to people.
The Adobe Creative suite logos are letters, but they are related to the Periodic Table and they are some of the best known applications in the world.
A simple J on its own is not good enough for a serious capable application in my humble opinion…
