Occasionally, as an opinionated designer-y type, I find myself getting a little obnoxiously pretentious and try really hard to reel myself in. However, when it comes to fonts, I would proudly wear the Queen Snotty-Pants crown if it meant eradicating the use of the worst offenders. Why am I so passionate, you ask? Because fonts are all around us. We face a constant barrage of tiny emotional responses from every direction nearly every hour of every day, and I'm sorry, I am just tired of being assaulted by over-used crap. When choosing a font, it should be back-up to your content, it should not BE your content. Many people choose fonts for the emotional tone they want to convey based on subconscious associational thinking (ex. I have often seen X font on massage therapy studios and spas, so I will use the same one). This thinking is fundamentally flawed because you have now associated yourself directly with your competition and/or their reputation. So, in business, it is of paramount importance to select fonts for BOTH their original tone, AND for their associational response.
This list was compiled through an informal survey of the multitude of marketing pros and graphic designers I have known over the years. Yes, we actually sit around talking about fonts over a beers at a pub. Stop laughing. Seriously, stop laughing.
For the love of god, this is the ugliest font ever designed. If you use it, I'm sorry, but it makes you look like a third-grader. It is not cute, it is not fun, and it conveys to customers that you would like to be thought of as juvenile. If you use it in a color like purple or yellow, you may need an intervention. If you have a visceral reaction to what I just wrote (either agreeing or disagreeing), you must also read this: http://www.mcsweeneys.net/links/monologues/15comicsans.html.
The moral of the story. When choosing fonts, your default choice should always be the simplest option. Yes, you want your font to convey a feeling, but make sure that feeling isn't contempt. Overall, legibility is also key. A font, no matter how adorable/sophisticated/different it is, is only as good at the content it represents. When in doubt, ask a designer. But, do not mine them for advice. This is what they do. Your questions for them end at, "Give me your honest opinion on my_________." If you want more help than that, PAY THEM.
