At most once. Links are what the internet is for:)
If you want links, here they are:

The thing is, those articles probably aren't brief enough for many people to stay interested, and they probably also don't go deep enough to make any particular one of impendia's results comprehensible. (And I'm also not sure if they're readable to people with only an engineering background in math.)
(In case you think I'm being snooty about engineers, I dropped out of college and have never published a theorem; instead, I have made my living writing software.)
But the OP's goal is simply to increase interest in his own work. Recurring concepts could be explained once somewhere and referred back to as needed, and the research and its implications could be elaborated on in far more detail than that given in the abstracts. This should not only be possible, but would likely be quite successful.
Mathematicians do have the advantage that all their papers are open-access. If you're interested in math, you can cruise on over to arXiv and read 60 abstracts an hour.
