You’ve seen it plenty of times before. A website loads but only the sidebar appears. The loading graphic in your browser is still spinning and there’s that “contacting …” or “loading …” message at the bottom of your window. Why?
I just noticed this happening on Pro Blogger a few minutes ago. Darren’s c2.gostats.com stats are loaded just below the sidebar and because that site was responding slowly the main content part of his blog didn’t display immediately. This may be a storm in a teacup because the next time I refreshed it loaded fine but remember, first impressions count. You don’t want to keep a new visitor to your site waiting.
