Well, in your opinion, are both commas used correctly in this sentence?

I enjoy a good semi colon; however, using them with 'however' can be confusing. Should I use a colon instead? Should Howevers be capitalized? 

How should a semi colon NOT be used?

I've been told that the hyphen is almost impossible to misuse - is this true, and if not, when not?

Is it generally accepted to use a third-person plural pronoun for inanimate objects?

For example:  “I like socks because they keep my feet warm.”

Also, to avoid sexist language, is it best to use he or she, make the noun/pronoun plural, or just rewrite the sentence? 

Examples:

“If a gamer wants to unlock all of Bioshock 2’s content, he or she will have to pay for it.”

“If gamers want to unlock all of Bioshock 2’s content, they will have to pay for it.”

“Gamers will have to pay to unlock all of Bioshock 2’s content.”

video game or videogame

I want to second/emphasize Jazz's second question: when NOT to use a semicolon?

Is it BioShock or Bioshock? I prefer the former.

Also, I know corporations are considered individuals ("Capcom is hiring" rather than "Capcom are hiring") but when can we use "they" to describe a genderless entity? Should I just use "it"?

EX: "SNK is a shadow of their former self" vs "SNK is a shadow of its former self"

@Nick N: It is generally acceptable to use "they" as a singular pronoun -- ie. “If a gamer wants to unlock all of Bioshock 2’s content, they will have to pay for it.” As for which form is most appropriate, I'll leave it to Jason to explain.

Is it ever okay to not preserve parallel structure?

I'd like some clarification on when to use parentheses instead of an em-dash (and, to a lesser extent, vice-versa).

Please enlighten me on the proper usage of hyphens and parentheses.

@Jazz: You shouldn't use a semi-colon and consecutive conjunction; the semi-colon itself acts as the connective. Unless the word after the semi-colon is a proper noun—and as such, would be capitalised anyway—it should be exactly as if you'd just used a conjunction, so 'John' is still 'John', and 'game' is still 'game'.

@Richard @Sandy If you guys answer questions, I won't have anything left for my post!

I'll add my voice to those asking about parentheses:

What are the rules on parentheses at Bitmob? You seem to like dashes, but are there any circumstances where you'd prefer curly brackets? Also, what's so great about dashes?

I still read a ton of stories in the Mobfeed with passive voice. Maybe you could write up a small lesson on how to avoid writing passively.

Great questions, guys. These are the exact sort of things we've had internal discussions about!
