1) you may still be able to run #plume, but I think it might not be getting fixes. (Does that matter???)
2) i use writefreely; it is relatively easy to set up, and is under active development, but (last time I checked) has NO comment facility, and it can be a bit laborious to create tables-of-contents/indexes, or add images. It has no search but does have simple hashtags.
Other features are promised ...
