One of the things with blogging is that there are so many different bloggers pursuing different goals and this can be a real strain on the developer. Some people want everything and the kitchen sink while others want just the basic functionality.
I think this is why we have MarsEdit on one side and Ecto on the other (taking more or less a kitchen sink approach). Incidentally, I think your acquisition might have given the Ecto developer a major kick up the rear because I see a screenshot
that looks a lot better than the product I know (still has ugly orange) and some pages "under construction".
So on one hand you have people who want you to make it easier to insert Amazon links (and maybe even search the amazon database), flickr photos, etc. while others just want the writing functionality.
Since a lot of the "flavor of the day" services bloggers use is transient and mainly involves pulling user data from a third party service I was wondering whether a "plugin/bundle" architecture wouldn help. You could create the system, document it and maybe include an example bundle for Amazon and Flickr. If others feel the need for more they can develop the plugins themselves.
Just a thought. Gosh this came out wordier than I wanted. Feel free to not respond. I'll be going through a bunch of ideas, bugs, etc. that I've been meaning to talk about while MarsEdit was neglected.
