I think it is a big mistake to underestimate the aggravation that the Coraline switch has caused to bloggers who are particular about what they put out there. The garishly yellow sticky feature is, without a doubt, an eternal affront to the senses. Ditto the fatter picture and avatar borders. As someone has already pointed out, they detract so much from the images they frame it's not funny.
Tthe people who gravitate towards Cutline don't do so on a whim. My surmise is that people who chose Cutline were people who had a professional bent. They would probably not touch some of the less-than-professional themes, let alone some of the other "garish" fare you offer. I think messing with this demographic's work, advertently or inadvertently, is really a big mistake.
What this experience has taught me is to watch my content closely with a view towards migrating some or all of it whenever a situation like this calls for it.
I deeply empathize with "Mvwphoto" and what he is going through. For websites that have a text and multi-media bent, Cutline has few equals - in the quasi-pro department, that is.
The guy who, characterized the backlash against the Coraline as unwarranted drama by "drama queens" in this thread:
is so out of touch with reality outside his peripheral vision it's not funny. I hope that WordPress staff do not feel that way behind a possible PR facade they are putting on here.
I certainly hope you bring Cutline back in some guise. Either that or you tweak Coraline to a point where it has the same spit and polish that Cutline had - which means deep-sixing that vomit yellow sticky for starters. Ditto the bloated frames around pictures and avatars. The tag cloud font sizes are wack, but they can be resized by tweaking the upper size percentages from 375% to like 175% max.
And while you are at it, the default setting should be set to not strip widgets when you or anyone else switches from from Cutline to Coraline. How on earth did that make sense when the designer for Coraline was coding this theme? This was supposed to be a replacement, remember? Other themes have not been designed as Cutline replacement don't do that.
