While I won't claim that my writing is very good I think I learned to handle the issue of writing sentences that are too long. It just takes a decision to allocate some time to reviewing your own writing and then looking at every sentence.
I don't do that for everyone of my LW posts, but if I would write a blog or fiction I would.
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. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
