Skribit had shut down on 2011–04–19.
Aside from WordPress this is longest I had used any blog-related service, even longer than Google Analytics and such.
At moment embedding options are rather flexible and very light. As for “How to install a Skribit widget” suggestion, native instructions on site or Skribit WordPress plugin make that rather easy.
Some consider tab intrusive, I also got this anonymous suggestion – “Don't follow the scroll bar with a stupid ‘Suggestions?’ box.” to which I can say – offer me non-stupid alternative and I will consider it. :)
Got quite a few suggestions over time. Good chunk of those were quite general and were only barely mentioned, some got proper extensive posts about them. Overall it is around twenty posts made on suggestions and about Skribit itself.
Some were not suggestions at all, it seems Skribit is easy to mistake for chat-box type thing or contact form alternative. Which it isn't.
What I lack in Skribit is momentum. Even if I properly cover suggestions made and my traffic is steadily rising, there is no increase in volume of suggestions. They are still very occasional.
Really, any of the several posts with extensive discussion provided in few days as many topics and suggestions in comments as Skribit had in a year.
I had some hopes for groups feature but it fizzled and was recently quietly cut to be reworked. Keep hearing about improvements coming. Well, those seem to take some time.
I think what is best about Skribit that it is no skin of my back. With initial performance issues fixed it is just there. Even if it doesn't get attention from readers most of the time it is completely worth keeping for occasions when it does.
Who knows, maybe those improvements will come some day and heat things up a bit. :)
