Why isn't Freebitco.in in the list? Isn't the place reliable?
Last time I looked they had a relatively high house edge (but acceptable on faucet site IMO) and a provably fair mechanism that could be improved: https://bitcointalksearch.org/topic/m.16023076
Overall I think freebitco.in is fun for free moneys and maybe trying to gamble that free moneys. But for real gamblers I would suggest other sites :x
I believe the same owner of freebitco.in owns KingDice now, so that is an option (or a site that I have listed
.) I actually followed KingDice for a while and kinda like the founder, but then he sold it hehe :p Obviously wetsuit has a long good (afaik) track record with freebitco.in, so nothing against him either 
If KingDice would be become more popular, I would certainly consider it to be added.I'm thinking about "investing" in Freebitco.in (getting the interest they pay), but I was worried when I didn't see it at your website.
You should be worried about any investment gambling site... Well maybe outside of betking they are the only ones i trust.
Why do you trust Betking in particular? There isn't even an investment option there, what's the point of leaving money there instead of in your own wallet?
I know the owner and they are following all the rules of provably fair gambling.
But generally casinos in my view should be privately funded like Primedice and Stake are.
care to elaborate why?
I always thought that publicly bankrolled casinos are more attractive since they offer
flexibility to a player-he can bet against the house or be the house itself
plus it adds extra transparency,since the bankroll is public and you can see how the casino is doing in terms of both profit and popularity (wagered)
Casinos like Just Dice, Crypto Games, Safe Dice, etc. are great because you can easily estimate your expected returns. The only thing hard to measure is the likelihood that the owner runs away with the money (a good filter is investing in the older ones, like Just Dice, https://bitcointalksearch.org/topic/investing-in-a-crypto-currency-casino-just-dice-2635712).
