I'm sure this won't come as a surprise, given I've made my opinion of the site fairly obvious in meta posts like this one and this, but I find the quality of our site to be very low.
Moderation Quality: I find the moderation on the site, both from the community and the mods, is very poor. Looking at our 50 newest questions, 17 of those have been closed. Of those 17, 14 (82%) of them had the deciding close vote cast by Robert. Of those 14, only 4 of them had a close vote from someone other than Robert (that number includes this question which was closed by robert, and later migrated by a site mod). The SE team shouldn't need to step in this frequently to help the community moderate when have 3 mods, and the site has been in beta for several months.
Site Scope: The site scope is poorly defined, which is evidenced by the fact that 17/50 newest questions have been closed. That, to me, indicates that our users don't really know what kind of questions are allowed on the site. A large part of this problem is that our primary scope is just "Everyday problems where the conventional solution isn't obvious or doesn't work", which just raises more questions than it answers, since it's an extremely subjective measure. With the exceptions of action take by Robert, our community tends to be very lenient in what's considered an "Everyday problem", which essentially has turned us into "Everything.SE", which we should very much not be.
We're also very inconsistent, something which is supported by some recent questions I've flagged.
The question https://lifehacks.stackexchange.com/questions/7598/how-do-i-get-rid-of-scutigera-coleptrata-in-my-flat was closed by Robert for the following reason:
Hi and welcome to the site. Unfortunately, general pest control questions are outside the scope of this site. See What topics can I ask about here? Sorry about the confusion. – Robert Cartaino♦ Jul 6 at 3:37
I strongly agree with this, and read this to mean this question does not require a "Lifehack" (aka it has a conventional solution), so I decided to go along and flag other questions with the same tag which had the same problem.
How to eliminate rats from kitchen?
Use mousetraps or hire an exterminator. This question is still open.
How to store bananas and keep fruit flies away?
Do exactly what the answer suggested, which is a fairly obvious and conventional solution. This question is still open.
How to deal with cockroach at home?
Hire an exterminator, as suggested by the appropriately named Caption Obvious. This question was closed as a duplicate, but I'd argue that's an invalid closure, since not being able to afford an exterminator (aka money) factors heavily into the kind of solutions which will work for each problem.
Which is the best lure to use on a mousetrap?
This is a conventional "How To" question. The kind of bait to use in a mousetrap is not a Lifehack. This question is still open.
I really don't see any reason why any of these questions should be left opened when that first question closed by Robert was closed, so this just indicates to me that our community is very inconsistent in applying our rules, which is likely caused by how poorly defined and broad our scope is.
Question Quality: There's been meta posts on this before, but I find the quality of questions to be very low. We get many questions where the solution is obvious (wait until the end of your shift), can be solved by a conventional solution (use earplugs), or would just be better answered elsewhere (ask our Home Improvement sister site instead). There's also questions which are just terrible, like this one: How do I safely clean a laptop using scuba gear?. You shouldn't use Scuba gear to clean anything, it's a terrible idea, and the fact that question has a net score of 10 doesn't reflect very well on our site.
