I'm not complaining, your name choices aren't grievances of mine. I couldn't care less about the name of a stranger on the internet.

I'm informing you that they're objectively going to lower your chance of success. Considering that it is "impolite" to tell that to someone, it becomes uncommon knowledge. Fortunately, I'm not a polite person.

For what it's worth, if I had any scientific evidence that having an Anime avatar on Github lowered your chances of success, I would tell you that as well.

I will leave you with this quote by Donald Knuth:

"The most important thing in the programming language is the name. A language will not succeed without a good name. I have recently invented a very good name and now I am looking for a suitable language."
