The last redesign, done back around 2011, was me sticking to the 3 column layout that I refused to give up because - well, really, I like 3 columns.
Mobile devices, on the other hand, don't do that many columns in a usable way. In fact, it's pretty damned annoying - so I opted for - and for the first time - a fixed width design. I've opted to diminish the prominence of KnowProSE.com (since I'm no longer running an LLC) and instead feature my own name, or brand, more prominently. And I tossed in some of my own images at top.
Why did I do these things? Honestly, I needed to simplify. I can do a lot of different things and I do a lot of different things. That has been a constant issue with my website(s) - I'm all over the place in my interests. Some time ago I decided that I would divide my sites into personal (also redesigned last weekend) and professional (*this).
Even that doesn't seem to be enough as my 'professional', while still mainly software development, is not limited to software development. In an age where employers and businesses seek specialists more and more, I have become more and more general. How do you do a site for that?
I don't really know. I'm still figuring it out while doing stuff to pay the bills. :-)
