[2/3] hashtag important - important, but not very
hashtag notimportant - not important
hashtag antiimportant - better to ignore
#importantFor_all - helps to restrict category of viewers who should this consider this much
hashtag maybeVeryImportant may be used together with hashtag important, maybeMostImportant - etc. if you aren't sure. I think we should gain some experience about whether we should use it right with tags #mostimportant etc.
