Similarly, Fireworks felt like it died the day Adobe acquired Macromedia. While it had a number of versions released after that it never felt like it was getting very much attention. A shame.
Yep, it still is puzzling why Fireworks never got the recognition it deserved -- the amount of unnecessary suffering UI designers went through for 10 years they could have avoided by just switching tools is mind boggling.
I don't think it ever got enough recognition for handling UI designs and everyone just gravitated towards Photoshop or Illustrator.
I think its heyday was when HTML table layouts were still how you had to layout websites and it's slicing capabilities were really convenient. I suspect that was the killer feature for a lot of people but once CSS layouts took over, Fireworks really fell out of favor and Adobe never bothered to reposition it as a UI tool.
I still use it to this day for my limited editing/mockup needs. The new workflow seems to be mockup tool (like Balsamiq) -> Photoshop design -> HTML/CSS, but for my needs, I can get reasonably close enough in both layout and design in Fireworks just do Fireworks -> HTML/CSS.
I don't know if a tool that is close enough to Fireworks to be a good replacement has come around, but I know it's definitely not Photoshop, which I find far too complicated for the basic tasks I need.
It's still available if you dig around on Adobe's site.
Despite having the full creative suite I still turn to Fireworks for quick jobs sometimes when I need to do a fast crop or slice job, or put together a simple 'constructed' image element.
