What do you like best?
It doesn't take much effort to learn. It's probably not more difficult to use than Microsoft Powerpoint. I used to use Frontpage years ago and since its demise, I switched to use this free software.
And, it's FREE (which is the major deal in my opinion) !
What do you dislike?
It's slow to start just like any Microsoft Office software.
And it's perhaps not the most extensive web editor. You can imagine more functions that can be added.
Moreover, "Microsoft Expression Web" is generally for a designer, not a programmer, I guess. This may be its biggest limitation, in my opinion.
Recommendations to others considering the product
I use this when the Frontpage stopped to be available.
I've used it both by editing the HTML as well as using the WYSIWYG portion. I've found this to be the most effective.
What business problems are you solving with the product? What benefits have you realized?
Sometimes, I wrote a little webpage for our group and our Dept. to help myself and other people to obtain information and keep the records for our groups.
