Ok Illydth, first their Kickstarter obviously made them enough to get this rolling. Second you say that it was only up for a limited time, too limited in your opinion, but then you go ahead and say that they did nothing to limit the amount of people. You've already answered your own argument. How well they advertised the kickstarter, and the amount of time it was up for, was there way of limiting.
Sorry Zinquox: I'm afraid I'm going to have to agree to disagree with you on this. While what you say is technically right, it's pretty much antithesis to what kick-starter exists for and why it's used in the business world. If the intent was not to obtain as much cash to finance a new venture as possible, there would be no such thing as stretch goals, multiple backing levels or all the other fun stuff kickstarters use to get people to pay $100 instead of $30. If their honest business plan not to be swamped by pre-access people was "limitation by obscurity" I would really question LWD as a company and the competence of the folks running the business...fortunately, I have absolutely no belief that what you are saying is in any way their business plan for the kickstarter, so my faith holds that LWD is a competent company with a good business plan and not a couple highschoolers in their mom's garage.

Second, your comment that LWD is "a company who's in business to make money," I have a feeling is more wrong then you can imagine. I highly doubt the people who started LWD said, "I know lets make money!" It was probably more something along the lines of, "Hey we could develop this product, and do an awesome job at it, we should do this!" Yes they make money off their product, but as this is something they do full time, they need to make some money off it, to you know, pay bills and other things.
*whistles* Ok, I like LWD too, but if you believe that their soul existence is because they like their product and it has nothing to do with paying bills, paying employees or making money, I have a bridge in Colorado to sell you.
Every company in the world exists for a single purpose: That is to make money. Otherwise LWD would be either a non-profit or an open source development effort. They make good products, they obviously care about them. Every company STARTS with an idea, but it continues to exist because of the money that idea produces. If you believe for a second that if the money dried up they'd still continue doing what they're doing, I think you're romanticizing quite a bit. Every professional developer cares about their products...they can't NOT and still produce something as great as LWD does. But LWD is a company, it DOES have employees, it pays taxes and it needs to produce a profit. I don't work for free...I can't afford to...and neither can the employees working for LWD.
If money didn't matter, they'd never have opened the Kickstarter in the first place.
My point is there are many of us who missed the kickstarter due to something other than our disinterest who would love nothing more than to provide LWD more of what it needs to continue functioning as a company: Money. Given the various delays in it's release schedule, there's absolutely no reason why more money would not be a good thing to infuse this project with at this point.
Third, yes I missed the kickstarter, and sure I would love to be able to buy in to help make this happen, but with so many people using it and reporting bugs, there really are only so many hours in a day, and too many cooks really can spoil the soup. I will wait. Is the world going to end because I had to wait a little longer? No? Good, then wait I shall.
If LWD is still in the "too many cooks spoiling the soup" position at this point in their development cycle, this project has more problems than anyone should be comfortable with.
When you open a beta effort you allow for a small number of testers for exactly the reason you allow: Small numbers of developers can't field fixes for hundreds of users. If LWD were still in the early development/testing phases of RW, your point is absolutely valid.
However as the development effort continues forward the number of bugs being found *should* be reduced and thus more testers do not produce more bugs...as each beta release hits the door more testers can and should be added to allow for more bugs to be found. If, what 3 - 4 Months? after opening early access they're still getting more bugs reported than the developers can keep up with...without adding new testers...this speaks to a larger problem.
Here's the flip side of what you've said: 600ish users is NOT enough beta testers to find all or even most of the bugs in a sufficiently complex piece of software. If they are NOT allowing for more testers, history and experience says many of the bugs will NOT be caught, meaning that at release the software will only be partially functional.
There's no better way to piss off your users than to deny them the ability to pay for beta access and then release beta quality software they have to pay for.
My only point in even posting was to suggest to the OP that there is another side to people complaining about the missed deadlines and not getting access to the software. Not everyone who wanted to had the opportunity to get in on early access. There are still many beta applicants sitting out there without access to the software. By the time you've blown your second or third self published "we'll release by here" deadline, people start asking what the problem is.
Suggesting "Well they simply can't handle adding more people, it would overwhelm them" does NOTHING to assuage people's fear that this product has gone off the rails. If that IS the case, if adding more testers at this point WOULD be overwhelming to the development staff, then the "Early 2014" release date published isn't even a pipe dream...unless they're going the route of releasing half done software and allowing the community to beta test it for them...
Which is all the complainers are asking for anyway...isn't it?
