It might be a tiny reduction, but I think that the start of a new era is now becoming more obvius. We kept seing mining becoming more centralised, mining at home kept becoming harder while the difficulty was constanly rising and the price was around 350. I believe that this reduction was caused by home miner being pulled off the wall because of not being profitable anymore.
It's possible that there was a genuine reduction in capacity, but with this small a difficulty change it's also pretty likely that it's just a result of statistical variances and we have no real way of knowing whether the network is expanding or contracting. In a network where there's no actual change in capacity, variances of +/-5% are pretty likely: http://hashingit.com/analysis/28-reach-for-the-ear-defendersIndeed it is, but mining used to be an arms race. The total network hashrate was constantly increasing for more than a year until this point. It's still an arms race, but the slowdown in hash rate expansion was predictable (I did predict it :-)) once everyone was running close to state-of-the-art hardware with low supplier margins and energy costs had been reduced as far as possible. Things can still move with a technology shift (such as when 16nm ASICs or more power efficient 28nm/20nm devices come online) or if the BTC price increases though. The hash rate will ultimately absorb every optimisation possible!

No. Mining will ne cheaper by factor 5x so the bitcoinprice will fell, before the hashrate unfold 5x. I would not either hold until 2017 halving. Not 100%. Maybe speculate with 5%

The issue with the arms race metaphor is this is a profit and loss business. Everybody experiences equipment dropout over time due to breakage. There is a difficulty level at which it is no longer economic to replace the equipment that wears out. Especially after the next halving. After the halving, I would expect a slow decrease in difficulty to a new normal. There is now huge uncertainty in future difficulty increases. The big players are facing huge uncertainty in their investment decisions. I suspect what will happen is, if difficulty stays flat for a few increases, there will be another round of investment putting us back on the upward trajectory. If it even starts increasing at 5%, the investment decisions get much harder at this BTC price.

almost everyone I know has taken their s1-s3s offline in california as the electricity is to much especially when btc price is at less than 400$ - If it went down about 20% I think some people may turn it back on but this was just a small one.

Well I see no difference, but as I always say... A reduction is better than a increase. It just shows me, everything is working like clockwork!

What I don't understand, the people selling their HW, is someone taking them to the shredder? Because you have alot of countries wheere power is next to free, so the old mining HW can still be efficient in other places, so why isn't anyone exploiting this?

People staying in the states, might find it not worth to ship or go start their mining operation in countries, where mining is profitable, due to very low power prices.

Does negative difficulty indicate that there is a slight reduction in the amount of total miners?

"Slight" not exactly, a farm shut or so, but yes youre on the right track

Interesting thing , but I don't think this is the first time that the diff. has been reduced ? Or am I wrong ?

You are correct, but it's the first time we've seen a decrease in almost two years.

Hopefully the difficulty will last few more months. I am sick of seeing the difficulty halt for 2 weeks and jump even more then the last month added up.

It looks like it may remain low, or even decrease again in seven days. That said, there's no telling when a new mine will come online.
