I just wanted to circle back to this topic. I apologize for my absence but had a stay in the hospital to deal with. I do see there has been activity in updating / bug fixes and that to me is somewhat encouraging.
To be honest I only use a couple of JA templates but choose to pay for a plan as opposed to buying individual templates as a way of supporting the developers.
I have been in the website design and hosting business for almost 30 years. I am not wealthy but it has allowed me a decent income. I'm now slowing down but still wanting to maintain my current client base, thus I'm engaged in upgrading sites /templates to J5. As I previously mentioned I was a user of JoomlaShine until they closed their doors. That left me in a huge hole trying to upgrade. So my needs are rather simple as opposed to others who might be looking for the newest templates. I'm more concerned with the longevity and stability of existing products.
As long as I see those at Joomlart engaging I'm happy.
Let me make it clear that this is just my personal opinion. I'm not here to judge other responses as they have their own merits. I was frustrated at the pace with which Joomla has been moving from J3 -> J4 -> J5 and soon to be J6 but that's the nature of a competitive market and I'd much rather be catching up to an emerging technology as opposed to placing Band-Aids on a dying technology. It gives me a better appreciation for all that Joomlart has to handle with keeping pace with the changes.
