I've been finding it hard to find code that I can actually review. I have no C# or web experience really, so I'm hoping when it goes into the public beta I'll have more code that is in C or C++ that I can help give some feedback on.
I think the number of unanswered questions is probably due to a mismatch of expertise, and going public may help with that.
I am pretty new to SO, and this is my first visit to Code Review. But I CAN tell you I was excited to see it. As a self-taught "enthusiast" I can say it will be nice to post some things and get feedback. I have no other outlet, and the guidelines for posts on SO are pretty clear about posting things like "What do you think of my Code?". SO for me, the ability to get some constructive feedback will really be a benefit.
The probelms I see (and others have somewhat pointed out) are:
That there will be many posts which should be on SO; namely, coding QUESTIONS instead of "Here's my code, please review my work". However, isn't there always a little cross - pollination, which is usually solved by a moderator moving the post to the appropriate place?
If this follows the pattern of some other forum-type sites I've seen the traffic here may not be as heavy as some of the Q & A Areas. However, I am betting for thiose who ARE on here for the stated purpose, it will be an invaluable resource.
Several commenters have noted that they are only "expert" in one language or another. While I am emphatically NOT an expert in the acedemic sense, I can say that certain aspects of good programming may transcend specific languages. Not always. But it can be rewarding for the reviewer to observe someone's otherwise well-thought out code, and spot a flaw that only someone with a different perspective on the problem might catch. Since multiple reviewers can comment, the worst that can happen is a Java expert makes an observation about another person's PHP code, and catches a problematic inheritance hierarchy that no one else did (as an example).
I am excited to see what comes of this site. THanks to those who are making it happen!
