I wanted to revisit the necessity of using ALT "tags".
"Alternative text is especially useful in the following situations:
* For people with low bandwidth connections, who may opt not to load
* For people using handheld devices
* For people with disabilities who use assistive technology, such as
refreshable braille displays or screen readers
* For people using a pay per transferred data connection
* Search engine optimization: most search engines interpret the
meaning of objects by analysing their alt attribute"
"Why should authors bother with ALT texts?
Well, from the fact that you're reading this article, I hope you already
think it's a good idea, but I have written some notes  on this topic.
Some of the biggest "casualties" on the information dirt-track are
documents whose authors didn't take the indexing robots seriously. Every
step that you take towards text-mode accessibility is, at the same time, a
step towards being friendly to those indexing robots, so (whether or not
you care about minority audiences such as the blind or users of text mode
terminals) I'd say it's in your own interest to keep text-mode
accessibility in mind. "
These gave me some food for thought about not using ALT text in my pages.
My previous post on this was a justification for not using them because I
felt all the info needed was in the text comments, quotes and links.
This seemed to me to make using ALT text superfluous.
But, search engine optimization does seem to be reason enough to use ALT text.
I wish I had a better idea how useful sight impaired users find ALT tag info.
I can't end this without stating another reason I stopped using ALT text.
All my pages have lots of images and I just never seemed to get around to
adding the ALT text because it was too much trouble and slowed the already
sluggish pace at which I work.
p.s. Is the "N.B:" above an abbreviation for nota bene, a latin expression
meaning "note well"? http://en.wikipedia.org/wiki/NB
I confess to being ignorant as to it's meaning.
