Adobe should spend their time and money investing in a resource for designers to learn and perfect HTML/CSS/JS techniques rather than building useless tools like Muse.
("Processing cycles on the printer's raster processor are incredibly precious! Can you imagine, this printing job would easily run 70% faster if only the PostScript document were hand-written instead of produced by some junky layout tool...")
99% of designers will never write code, no matter how exciting educational prose and tutorials we may come up with. It's a shame to drive away those designers from the web just because of old-fashioned HTML snobbery.
History has shown us repeatedly that these sorts of wysiwyg programs write really bad markup, which is a symptom of their pretending that HTML is capable of things that it is not.
That was unavoidable because HTML wasn't capable of doing the kind of layout that designers wanted. This was back in the late '90s, when the demand for WYSIWYG web design tools boomed but the HTML standard was splintered by incompatible vendor-specific extensions.
We can do much better now; hopefully Adobe Muse does.
Sometimes I wonder if aligning our values with those of ordinary people wouldn't yield better results than thinking up uses for the <aside> tag.
