I've noticed a few questions and answers that are high quality and valuable, but appear to have typos or missing words in places. In cases where I understand the meaning, I can simply edit to correct this. However, in many cases I'm out of my depth and simply can't guess what was intended - especially when terms are us... |

The site was off to a strong start, but participation fell off a cliff about a week in. Was it the SIGGRAPH conference? Or maybe there are other SE sites these question can be asked.

For a moment it looked like the private beta had been shut down. Resurection seems a bit omnious. Lets try harder shall we. Invite friends.

We've been [given an extra week] to prove we are ready for public beta. We've had that week, and more. We still haven't progressed to public beta. However, we still haven't been shut down either, apart from [temporarily accidentally].

Once you get access to the review queues, one of the review types is "First Posts". Here experienced users are shown new users' first posts and asked to take an action.
What should we do at this point? I've just completed my first "first post" review, and the answer was good so I upvoted. I couldn't think of anythin... |
How should we welcome new users? |
In my opinion we should handle posts in the First Posts Queue and the Late Answers Queue the same way as posts we find when browsing questions usually. You don't post a comment when you find a "normal" post of a regular user, if you have nothing to say. Why do it for first posts?
Personally, I handle first posts *mo... |
While on some SEs, notably Stack Overflow, it is often sufficient for questions to contain a short code snippet, others, notable TeX/LaTeX SE, ask for a full [Minimal Working Example (MWE)](http://meta.tex.stackexchange.com/q/228/18957).

A specific question about the internals of a specific system should be on-topic.

If I got the *vibe* of the Area51 proposal that I thought I did, this stack is for computer graphics **theory**, **research**, **programming**, **implementation**, and anything similar to such focuses.
As such, there would be quite a bit of overlap if it included app-specific *modeling* questions in general.

Are questions about procedural noise on topic? |
The reason why I raised a VTC flag is because it doesn't ask a question regarding computer graphics, specifically. Noise generation is useful in many fields, not just computer graphics (or programming in general). It's a mathematical algorithm that isn't graphics specific.

Yes. How better can you demonstrate a graphic effect or make a qualitative comparison? Some good examples would be animation, IK, shaders, etc. I feel like this is obvious. |
I dont really understand how it could be possible for it to **not** be in scope. It is:
