I think these are great news. We don't need any development (since 23hq is great from the start) but we do need the existing features to work.
In the mean time I stumbled upon another user's page in 23hq where he says he has developed an Android App for 23hq that allows for some features besides viewing. I have installed the app and found out that you can post comments using the app.
The user's page in 23hq is http://www.23hq.com/ise_80 and from there you can get to the app page on Github.
A few final issues.
If we want 23hq to continue existing we should try to bring more people on board. Invite friends, family or work colleagues. We should also try to have as many people as possible to become paying users. A 23hq subscription is still quite cheap compared to other similar services.
The same applies to the app, which looks great, but has not been actively developed for 3-4 years. We should all thank the author, encourage him to continue developing the app and, if possible, donate for his effort.
