I don’t know what is the specifics as to why, but when I see a poster or something, I can instinctively feel if it is made with Canvas. I don’t know if it is the font, colours, how generic the templates are, or if it is the stock images, but I instantly feel a repulsion towards said graphic design. It doesn’t matter what style or vibe it’s going for, but I instantly hate it.
Not sure what you mean by qualified. Edit: I looked it up and it seems like adding the http part, but why would that prevent someone from clicking the link? For me it worked fine.
Might depends on your chosen interface/browser.
