I'd like to add my own comment here.
Firstly, I had deleted all my previous posts and content because I basically got pissed off with @Traumflug and others about their viewpoint that this community is to serve users of TB and not to serve merchants - people were asking valid merchant questions that he deemed off topic for these forums.
Anyhow, I've been watching the posts to keep an eye on the project and felt strongly enough about this post to re-activate to give my viewpoint.
I paid into the Elastic search module $75 because I felt it was worthwhile. I was concerned it took so long to develop and when it did come out it was useless to me on a shared server. I know there's been various versions since but I've not bothered looking at it as I feel TB still isn't good enough to switch to from PS.
The point I'm trying to get to is this... people shouldn't expect a free ride, if you want the software I think it's more than fair enough to pay for it BUT the reason why I and probably many others haven't taken the plunge is because you've got no business plan - you've tried the coin hive thing, you've tried paying for making modules and now this Patreon thing yet there's still no 'this is what we're going to give'...
On PrestaShop they've got a dire 1.7 that seems to be getting worse but their plan to make money is to make you pay for it from modules. Lots of open source platforms do this. On the flip side here, you've got what seems to be 1 dedicated developer who is still tinkering with the elastic search, other devs who you don't know what are doing and no plan in place other than 'we're fixing the modules, tidying up some stats modules, fixing this or that'.
If you want this Patreon thing to work you need a clear plan of who the developers are, what happens if @mdekker suddenly decides he's had enough, does that mean TB ends? What the other devs get paid if anything? And also as @Traumflug pointed out in another post about the warehouse theme guy using WooCommerce because it was easy to setup - TB needs to just be installable, no 'you've got to do this, that or whatever' to make it work.
The way it seems to be going is TB will be a paid service not open source, which in my mind is a good thing, $20 a month gets you lifetime support - it's cheap enough for everyone and you know what you're signing up for, none of this 'pay this to get this or whatever'.
Bottom line, forget about all the bells and whistles stuff, just get it working so it works on everyone's platforms and make it a subscription service, only then move onto nice new stuff to add.
