There are only like 273 questions excluding this one. Mean while, there are over 18,000,000 on SO. Why is it so lonely here? Is anybody home?
You are on Earth Science Meta. This is the site to ask question about the site itself. Those are naturally fewer in number.
There are currently 5,008 question on the main Earth Science page. This is much less than on Stack Overflow. This is because the site is lesser known, newer, and covering a smaller topic. Earth Science will always be smaller than Stack Overflow. This is not a problem, as long as Earth Science gets a critical mass of users and a good signal to noise ratio.
Note that Stack Overflow has 41,486 question on meta vs. 18,912,994 on main, or about 0.2% meta vs. main questions. We have 274 meta questions vs. 5,008 main questions, or about 5.5% meta vs. main, so relatively speaking, our meta is much more active than the one on Stack Overflow. This is probably also normal because we are a smaller site.
