The old web site worked well! I liked it. No reason to change it...
other than the fact that today things *have* to change at regular intervals or you're not making progress. If you're not continuously changing, you're doing it wrong and losing customers. You have to make progress, right? If you're not making progress, you're falling behind, right? So you have to continuously make changes whether or not it's needed, right? New folks looking at it (ON THEIR PHONES) will not realize what the old site looked like and will think it's a great web site! Those of us who were comfortable with the old site, well, ... keep up or drop out. That's the mentality for everything now.
Don't ya just love progress? Welcome to the 21st century.
