Font is one component of a design. The selection of appropriate fonts for a logo will greatly affect the interpretation of the company. Elegant fonts indicates a professional company. Fancy fonts indicates a trademark of funny, cute. We can easily find thousands of fonts. Haha I sometimes confuse to pick it up. Of the thousands of course there is the font type that I would not use it. No offence to the font designer is only my personal opinion.

Type font is not possible I use is as follows:
unreadable
font is a text that aims to get people to read and recognize his trademark. if the font can not be read, then how could represent a trademark
weird
designers may want creativity, but sometimes there’s just a strange font types such as symbol
inconsistent
form of alphabet letters is inconsistent as not to show one type of font

This is only a personal opinion only. I really liked the combination and played with various types of fonts. It requires tremendous creativity of great font designer.
