Companies are always feeling the pressure to relaunch their sites optimized for all the new versions of browsers. And rightfully so, I might add.

But here's my thought for the day, a great way to rope in the new may be to not forget the old. What do I mean? Don't forget the folks who don't upgrade their systems until they absolutely have to.

Here are some interesting statistics to ponder on the most popular browsers, as of June 2007. As you might expect, the latest, greatest Internet Explorer 7 is catching on at just under 18%. Internet Explorer 6 still reigns supreme at 37%. Firefox is nipping at its heels at 34%.

However, check out the bottom feeders.

Internet Explorer 5 may only makeup 1.5% of browser users out there. But, we are talking about a browser that was released eight years ago and supplanted by IE 6 in 2001. As you think about that, consider this: as old as IE 5 is, it still beats out today's Apple Safari browser.

If your web team is knocking themselves out to optimize for Safari then why not Internet Explorer 5? There are actually more people in the world using the latter and not the former.
