Heheh. It's standard practice to publish content in a normal way and let people's own preferences work for them. If someone wants text at ctrl +, they'll already have it set that way. To publish so that everyone who wants standard text has to ctrl - is to communicate a lack of caring for the reader, which doesn't help promote more readers.
I considering resteeming this post, but I have to agree with Kevin here. The size of the text is a bit much.
