So, given the last two comments it appears that I am going to put forward what may be the contrarian view (ooh, “contrarian”, I like that word - must use it more often).
I believe that there is a difference between the discussions that we have about Clozemaster itself, and the discussions that we have that are related to languages/sentences.
For my part, I do agree that having the discussions about Clozemaster itself kept to Pro users is probably a good thing. My reasons for sitting on the Pro-only side of the debate for these types of discussions are numerous. A large part of the reason is that what we discuss such as features, feature requests, “how best to use Clozemaster” type discussions etc., are typically very heavily biased towards - or reliant on - features that are only open to Pro users. In these cases I’m not sure of the added value that might come from having non-subscribers being able to participate in these discussions. I would conjecture that periodically, the contributions from some non-subscribers would be mostly about appeals/requests/demands to have those Pro-only features made available in the free version.
On the subject of opening up sentence discussions to non-Pro users, I have a very different opinion.
With the single exception of Italian, there is hardly anybody engaging in sentence discussions from the Pro community. Italian typically has around 5 to 10 people who will contribute to discussions, and amongst those people there is one person who is a native speaker who sometimes offers advice and contributions (together with @Floria7 using her madrelingua contact as an “external consultant”). The only other languages that occasionally appear to have multiple contributors are Spanish and (infrequently) German.
In other languages there are normally no more than 3 people contributing, typically it is just 2 people, and some of those are almost student-tutor discussions where a native speaker is kind enough to provide the clarifications, tips and advice to a learner. For many languages, the sentence “discussion” is simply someone posting a comment about a sentence and … that is the end of the “discussion”, as there is nobody out there with whom to discuss.
This has been mentioned on several occasions on this forum as something that limits people’s enjoyment, or that people see as a weakness, of Clozemaster, such as in this recent example mentioned by @galning -
I believe that opening up sentence discussions to non-subscribers would be beneficial, particularly for languages and language pairings that do not have a large user-base of current contributors (which is pretty much everything that isn’t Italian). Given that Clozemaster has a much smaller user-base than Duolingo the other place, I don’t think that this would make the Forum too noisy - particularly as the sentence discussions section is excluded from the “Latest” feed and front page of the Forum.
Also, there is very little discussion that goes on in the “Language Specific” category, and so again that could be something that could be worth considering opening up.
Furthermore, there could be a good argument to open up the Bug Reports section to non-subscribers as well, given that we would all benefit from the reporting (and resolution) of bugs.
The idea of having selected categories that were open to non-subscribers is something that @mike seemed happy with 2 years ago -
I would be very happy to hear what people think about opening up the sentence discussions (and possibly language specific and/or bug reports) categories to both Pro and non-Pro users, and leaving the rest as Pro-only.
