Before this proposal went into beta, Tim Post laid out some ground rules on Area 51. If you haven't read them yet, I strongly encourage you to do so. The problem, a lot of you guys aren't following them, and it's really bringing down the overall quality of a just-blooming site. It's beginning to look an awful lot like Yahoo! Answers.
My main concern here is with the answers being posted on this site, and how much like pure spam they look. Let's keep in mind here that the name of the site is Software Recommendations, not Software Lists. That means you should be recommending software, not just going to Google, searching for something that matches, and posting a link to it with some vague description or "this does what you want." That's just plain not useful, and some of you might notice that I've cast quite a handful of downvotes already on the main site.
Let's quote a very important line from Tim Post's Area 51 guidelines:
Good answers on this site will be in the form of honest testimonials that share first hand experience with something and why it meets the needs of the asker.
You should answer questions when you have first hand knowledge of things that satisfies at least most of the constraints given in the question. You should be ready to talk about your experience with it, what you liked about it, what features it does (or perhaps doesn't) have, within the context of the question. You should also talk about any potential quirks that you can think of, and even things that you found to be a down side of the product. In short, share your experience with something, not simply your knowledge that it exists.
Now, I don't even need to link answers here because you can browse through just about any question that has an answer so far and see examples of users not doing this.
Some questions to consider answering when you're recommending your software:
How does it meet the needs of the asker? Don't just say "it has these features" or "it meets all of your needs" - who cares? Describe the features in more detail.
Why do you, personally, like the product? What other niche features does it have that the asker didn't even think about that make this product so great? Don't limit yourself to the constraints of the question. Remember that the question should be useful to future visitors, who may be looking at other things in addition to those criteria. Sell it to everyone.
Why is this product the one the asker should choose? What makes it stand out above all the other possible products? You should be taking the stance that this is the only option and you are trying to convince someone to use your product, even though it's not yours (or maybe it is, in which case, provide disclosure).
Back up your details! If you throw out any statistics about the product whatsoever, for heavens sake have a source!
Of course, there are some other basics that I've seen:
Include the name of the product. Like seriously, why would you ever post an answer that links to a product and does not ever mention the name of it in the post? I shouldn't even have to mention this...
Include a link to the product. Just naming a product is like a reverse-link-only answer. We shouldn't need to go to Google and search for the product you mentioned. Again, seriously?
Some of you know I came into this proposal skeptical and assuming it would fail. I'd love to be proven wrong, but what I've seen so far is not very promising.
