Of course, "parent" takes up less space, but the first comers may think it is a link to a board discussing children upbringing.
This was discussed briefly in the blog comments
I considered and discarded a lot of the alternatives, such as
- main (too close visually to meta)
- parent site (too long)
- actual name "english", "boardgames", "cooking" (too variable in every sense)
Main isn't bad but consider:
tools | chat | meta | about
tools | chat | main | about
They're so close visually.. ugh.
edit: since this kept coming up across the network I decided to change it from "parent" to "main".
