I've been trying out the "ferretwilliams" username on several sites for the past 4 months, and so far I've only been addressed once, and the name I was addressed by was "Williams". No. The purpose was not to have people call me by my last name, it was meant to incorporate my first name in an easy-to-spell way, plus to stop people from calling me "Will". If the username makes people address me by my last name(not even a "Mister" beforehand), I don't consider it an effective username. It just feels so... formal. Plus it's a pretty common last name.
I do like the name, though, because FERRET. Not only is it a good name, but it also has something to do with my comic. It's just the results of using the name that make me unsure about it.

Right now, I'm considering going instead with the name of a project I'll be revealing on Wednesday. It's a catchy, unique name and I own the domain name(no, it's not icwutudidthardotcom, which is a side project). Only issues with this currently-secret name is that people will be calling me by a phrase instead of my name, and the project is only planned to go for 4 years. It's likely people would call me just by the first word in that username(like how people shorten movie titles), which I would totally be fine with. Hmm... now I wish I had named the project something that starts with "Awesome", which would be even better!

I feel like maybe I should just go with garrettwilliams, but not only will it constantly get mis-spelled by people("garret"), the name is also taken on Twitter. Yeah, I need something I can use across several websites.

And no, I can't use "kennychronicles". I already have people calling me "Kenny", which is okay, but it's not my name nor fursona.
