Almost everything you said was wrong. cool.

Serif fonts originally came from a holdover of stone cutting. The serifs were cut in to the edges of text because it kept them from chipping and degrading as quickly. (squiggles? lol).

San-serifs came into popularity in the late ’50s because they looks more modern and were used to differentiate more classical from the newer or more modern / progressive signage and print.

Helvetica, verdana, and related fonts? heh. Fonts are based on design… they can be designed using pixels or vectors. Has nothing to do with the font design itself. While serifs traditionally were harder to read (10+ years ago)… sub-pixel anti-aliasing fixed this so that serif fonts now are generally readable on most computer displays. Verdana was specifically designed for online presentation by having letter shapes and kerning that worked well with digital displays. Since no display actually works on vectors but instead works on pixels… it doesn’t matter (from a display standpoint) what the file is. I highly doubt that helvetica (designed in 1957) was done with vector files in mind.

The problem with comic sans is that it is, typographically speaking, a niche font. With the introduction of wysiwyg document editing available to everyone… people started throwing tons of different font faces into their documents. You end up with a lot of people that see a font and think “oh, that’s fun” and use it… but without understanding how a font will work or how to properly lay out a document… what you end up with is crappy looking documents. Usually they try to combat this by adding more fonts… colors… and god-forbid word art. Designers hate this because comic sans is just a boring, overused, and in large quantities… ugly font. It makes most documents look sloppy and unprofessional… and most people will perceive this even if they don’t understand why.
