When a proposal gets in the commitment phase, you are asked to spread the word and let everyone know that such a site is about to start so that they can commit to it.
However, is it really useful to advertise the site to users that are not already member of another Stack Exchange site? For example, they don't seem to give much weight at all in getting through the commitment phase. Also, they are not familiar with the system and so are maybe not very useful or even annoying/harmful in the first precious hours/days of a site.
Should commitment only be for users with at least 500 on other sites? Or should referring the website outside the Stack Exchange network be discouraged until the public beta phase?
Another thing is, an outside user will not have much clue what the commitment exactly is. Their initial experience might be negative because there is nothing else to do than to click a commit button and wait anywhere between 1 day and 1 year.
What do you think?
