Ask HN: What features make a good blogging platform for you

Its funny that there are so many blogging platforms our there but I (and some people I talked to) still feel that there is no one place that fits all their blogging needs.

One key fact I believe is they are all too concentrated in making one platform and imposing it on all topics while the fact is that different bloggers have completely different need?

If you guys can share your thought on what you think should be a feature of a blogging platform? And do you think there is a need for a new one now?
