Hmmm ... OK, since you solicited it, I'll give you my comments and insights.
First off, there are MANY reasons why people might want to solo dive that have nothing to do with the quality of a potential dive buddy. Sure, buddies can assist you with all the things mentioned in the second paragraph of the article ... but if you're having those types of difficulties, you probably shouldn't be considering solo diving in the first place.
"Inconvenient" should never be a reason to make any dive planning decision ... solo or otherwise. The mental process that goes into your dive plan needs to be a bit more pragmatic than that, and include an honest assessment of the risks involved.
Then there's the assumption that dive photography and buddy diving are mutually incompatible. They're not at all ... you just have to know how to do it, and have a buddy who is willing to be a part of a team, rather than another diver in your general vicinity at the same time. I routinely engage in underwater photography ... as do many of my diving friends. Sometimes we go alone, and other times we go as buddies ... it depends on the dive profile and the reasons why we're going. It doesn't take much effort, really, to learn how to be both an underwater photographer and a responsible buddy ... it only takes a commitment to learn and a bit of self-discipline.
Finally, the article reads like a commercial for an SDI Solo class. The fact is that most solo divers are self-taught, and while a solo class might be helpful to a relatively new diver who wants to try solo diving, it is probably not going to provide the experienced diver with much in the way of useful information.
The answer to the solo diving debate isn't to get another C-card ... it's to make sure that you have honestly evaluated the risks associated with solo diving, have taken steps to mitigate those risks, and have the skills and mental discipline needed to self-rescue should you find yourself in an unanticipated bad situation.
Perhaps in some parts of the world a dive charter would not allow someone to solo dive without the SDI card ... but most solo divers are independent-minded enough to prefer avoiding operators who put those kinds of restrictions on their clients.
It's a mindset thing ... which is, in fact, what solo diving really boils down to ...

Thanks for those comments Bob, we agree on a lot of things:
You're right, there are MANY reasons why people want to dive solo, but as Afterdark's and other's comments reveal, the biggest is that they don't want to be inconvenienced. I've heard this on dive boats for the last 20 years.
You said, "Inconvenient" should never be a reason to make any dive planning decision ... solo or otherwise. The mental process that goes into your dive plan needs to be a bit more pragmatic than that, and include an honest assessment of the risks involved." and I couldn't agree more completely. This is one of the main points of the post.
You also made the point, "Then there's the assumption that dive photography and buddy diving are mutually incompatible. They're not at all ... you just have to know how to do it, and have a buddy who is willing to be a part of a team." And I couldn't agree more. They shouldn't be mutually incompatible. I know a number of u/w photogs that make great buddies but a lot more that don't.
"Finally, the article reads like a commercial for an SDI Solo class." Sorry about that but there aren't a lot of other options out there short of more advanced tech training.
"The fact is that most solo divers are self-taught, and while a solo class might be helpful to a relatively new diver who wants to try solo diving, it is probably not going to provide the experienced diver with much in the way of useful information." It is important that we address the new solo diver and this does that. Also, I see a lot of current solo divers diving without a redundant air supply.
"The answer to the solo diving debate isn't to get another C-card ... it's to make sure that you have honestly evaluated the risks associated with solo diving, have taken steps to mitigate those risks, and have the skills and mental discipline needed to self-rescue should you find yourself in an unanticipated bad situation." I agree completely with your mental assessment of solo diving. If there is no "formalized" training for this, where do you think people should get the experience?
"but if you're having those types of difficulties, you probably shouldn't be considering solo diving in the first place." Couldn't agree more. But those are some of the people that are solo diving and the guest stars in DANs Annual Report.
"Perhaps in some parts of the world a dive charter would not allow someone to solo dive without the SDI card ... but most solo divers are independent-minded enough to prefer avoiding operators who put those kinds of restrictions on their clients." Its unfortunate that we live in such a litigious world. My preference, as yours, is to let people take responsibility for their own actions and diving decisions. Unfortunately, that's not how the courts work anymore.
