Sure, that's what the open thread is for.
I haven't spent enough time commenting on LW to be sure enough of this, but it doesn't seemed to be used that way. Do you think it's used that way? If not, perhaps it would be beneficial to make it more clear that it can/should be used that way.
Also, maybe it'd be a good idea to break the open thread into categories. Eg:
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
