I've been fiddling with my blog a fair bit, which prompts this post, but this could as well apply to any website. Is there any metric or tool that can help you decide when you have gone too far with sidebar or widget additions and your site loses the snappy clean look you perhaps had in mind when you started out? I certainly wanted a nice clean look to my blog and was happy with Chyrp! as giving me a good headstart on that. But of course then you want to add content and interest, and one widget leads to another. Now I am wondering if I have gone too far, especially with the recent additions of twitter and digg entries. Of course a lot depends on the responsiveness of the widget hosts. It occurred to me there could well be a tool out there that will help you weed out any offending lag culprits... Or maybe this is a subjective matter and you have to monitor it yourself "by hand" so to speak. Opinions and offerings appreciated, as always (blog on sig).
