Remove ambiguous bi-yearly usage

[Bertg]

In English "Bi-yearly" (and similar expressions) are ambiguous. It could mean twice a year, or every 2 years. So let's stop using it.

On the front page we use (Bi-)Yearly weekend gathering for Ruby Camp, So let's replace it. Some suggestions:

• Weekend gathering, twice a year
• One weekend, twice a year
• One weekend, once or twice a year
• One weekend, about twice a year

@Bertg Agreed, always found it ambiguous too. Lets change it. @otagi @toch What do you prefer ?

I like "One weekend, twice a year".

The first one is not clear if it's the whole weekend, or an afternoon during the weekend.

The last two imply doubt about the schedule. Let's be publicly assertive instead! 😉
