I'm a member of the Community Management team here at Stack Exchange; we're the ones responsible for determining when each new site is ready to move on to the next stage of its life cycle.
It's been a week today since this site entered private beta. I'm really impressed by the enthusiasm here, and the helpful attitude folks are showing one another. But there are a few problems that need to be addressed before we'll be comfortable opening this site up to the public.
What is on-topic here?
There've been several discussions toward this end, but not nearly enough. This has the potential to be an enormous topic, but it is important that y'all work on defining the limits - focusing on what's actually being asked. The scope here can be as large or narrow as needed, so long as questions within that scope are answered effectively.
Original content; more than just a Hinduism primer
There are a lot of questions here that are... Pretty basic. "Could be answered by a Wikipedia entry" basic. Questions that require no expertise aren't a particularly good way to attract experts. You gotta expect a few of these, but when every other question can be answered by a Google search...
...And worse yet, an awful lot of them are answered that way: by quoting external sources. A site that just regurgitates things that others have written isn't much good; answers like that just clog up search results without adding anything. It's important to cite your sources, but just as important to demonstrate knowledge of both the question being answered and the topic itself - this is where we can actually make the Internet a better place, demonstrating how to use this knowledge to answer specific questions. Answers that are primarily copied from Wikipedia or other forums / blogs - even when properly attributed - are just speed-bumps, annoyances to folks searching for good information.
I'd really like to see more questions that require some serious research and experience to answer... I know some of you have been studying these topics for years, and are well past the beginner stages of your education - what sort of problems do you encounter?
Focus on facts, accuracy
There are a lot of answers here that amount to little more than anecdotes or opinions. Many of these may be useful - but how would someone with little experience in the topic know this? Show your work and back it up, and encourage others to do likewise!
This may seem like a small thing, but there's an awful lot of poor spelling, poor grammar, and poor formatting cropping up here. Some of you have been doing a great job of editing these into shape - kudos! - but it's still a problem. (Related: Please use consistent spelling in your posts)
We'll review this site again on Monday, to see if it's ready for a larger audience - in the next four days, let's try to sweep up and get it looking shiny!
