By web content guru Gerry McGovern:
If you don’t have good metadata and appropriate classification, then your content becomes much harder to find. Your search will become much less effective and your navigation much less useful.
Content management must always be about quality first, quantity second.
Prioritize. Limit. Choose. A relentless focus on quality should be at the beginning, middle and end of your publishing process.
The same is probably true for personal weblogs, albeit to a lesser degree. But if you ever want your weblog be read by others, paying attention to content quality seems a must to me.
