It's definitely unusual how inactive this forum has become over the past year or two. Technology wise, the hobby is in a great place right now. Cheap and readily available laser diodes in red, green and blue provide us with a powerful laser in almost any wavelength we want. The only areas we haven't seen much progress are in yellow and 488nm lasers.
Prices have also gotten much better compared to the early days of the laser hobby. DPSS prices have fallen by >75% in some cases. Prices on ebay are stunningly cheap now. You can get a true burning 450nm laser for only $50-$70. You can get a relatively decent 532nm (303/301lasers) for $7-8 shipped. 3 packs of overspec 405/532/650 for $7 etc. Never before have lasers been so readily available and affordable.
I remember this forum back in the 2008-2010 days when there was a huge amount of activity despite less available products and higher prices. You would naturally think things would be equally if not more busy around here today with all of the progress right?
Here are what I consider to be the contributing factors to the decline of the laser hobby and this forum.
-As one member suggested, I believe the decline of Wicked plays a part. While wicked were far from the best products or deals, they were GREAT at generating hype for the laser hobby. Their adds in magazines and other social media drew tons of people into lasers. Now that they no longer ship to the US and no longer advertise we've lost an important recruitment tool.
-Laserglow was another company which would advertise in scientific magazines and they've also stopped shipping >5mw to the US. The companies which still do ship >5mw lasers to the US tend not to advertise a whole lot.
-As Alaskan suggested, the novelty factor has somewhat worn off. Having a quality burning laser in the early years used to get you some real bragging rights (A burning 532nm capable of lighting matches would cost you a few hundred dollars), and now you can get burning 532nm's for like $20 from Sanwu. With the cheap prices and ready availability of lasers these days the 'exclusivity' of the hobby has somewhat worn off. Nobody gets all that exited anymore by a youtube vid showing a green laser popping balloons, lighting matches or burning through a newspaper. It's like what would happen in the auto world if everybody could get a high end sports car for <$20,000. Suddenly the special factor would decline by quite a lot.
-We have seen a slight stagnation over the past year or two when it comes to new developments. Still waiting on progress in the yellow and 488nm areas. Nothing groundbreaking has come out in years now, and hobbies thrive off new developments.
-The whole sci-fi lasers issue may have hurt this forum more than people realize. I mean the main official site sponsor decided to start blatantly scamming EVERYBODY, and it went on for several months before totally blowing up. Eitan likely ripped off HUNDREDS of forum users and possibly caused them to lose interest in the hobby and this forum in particular. Especially bad was how long it took to pull the banner adds after the extent of his scamming was revealed.
-Lurkers: It seems like this forum has a massive amount of lurkers sometimes. I'll see like 1500+ people browsing the general section alone, and none of them post anything. Somehow we need to encourage people to actually get involved and post stuff.
-As another guy suggested, the forum name could use a little rework perhaps. It's just not 'exciting sounding' to people who come across it.
Things I don't believe are directly responsible for the decline:
-The negative press regarding laser attacks. Generally negative press and threats of bans are great at encouraging more interesting in a hobby as many people will try to stock up and learn about the hobby while they can. See what happens with gun sales in the US after events such as Sandy Hook for an easy example of this. Suddenly people want to buy up everything in sight before big govt can ban it. The negative press has only indirectly decreased interest in the hobby by causing wicked and LG to stop selling here.
-Financial issues. We're past the trouble of the 2008 financial collapse and the stock market is in great shape. Seems like people should have plenty of disposable income for hobbies such as this. The products have also gotten much cheaper as stated above.
-Safety concerns: See negative press. Hearing about how dangerous something is generally drives more interest.
-The trolling: The level of trolling here is honestly nothing compared to the level seen on more popular forums. The only way it would hurt this forum is if it causes members to react more harshly to new guys asking dumb questions. Everybody asked dumb "Is this laser any good" types of questions when they were starting out. Yeah, they could search the forum and see the "what company to buy from" thread, but let's be real here, people usually don't do that.
So how do we fix the situation?
-There are no easy answers that I know off.
-Forum giveaway style threads might encourage more lurkers to sign up and post here, if only to have a shot at getting a free item.
-New tech developments like yellow laser diodes or affordable 488nm would probably bring some interest back, but those aren't guaranteed to come out soon/ever.
-Community goals as suggested by the OP might be one way, but those would appeal mostly to the people who are into lasers for the science. Wouldn't do much to attract the people who just want cool tech gadgets.
-Make sure you put out awesome youtube videos sometimes. Those are great recruitment tools for this hobby.
-It would be great if we could somehow make this into more of a laser AND flashlight forum. I realize we have a flashlight subsection, but it's pretty dead. The flashlight crowd seems to be substantially bigger than the laser crowd, and if we could attract some of them here they might cross over and get into lasers also.
-Maybe add in a political and current events forum? People love posting in those.
