Discourse software offers suggestions even before we completely type our question. In some forums even if we have just started and is typing the title, Discourse will show threads similar to it.
While you can say that it is getting into our browser and spying on us, there is a good chance that it will avoid duplicate threads. And in the eyes of an end-user, answer even before they ask it.
What do you think of it ?
Discourse has it in the core. I haven't seen anywhere else other than StackExchange. Other software might have it, but as plugins.
Abhi What do you think of it ?
I don't know. Sometimes it is annoying, but when we can already find an answer, that feels good.
I have seen in Invision board sometime back. I am not sure what is the status now. Need to check and see the status.
