It's a natural thing, but for most of us, a slow thing. CamWorld wasn't built in a day. The key to building readers is to be interesting and the key to that is to be yourself. This all might sound odd coming from me. Kestrel's Nest is by no means a popular weblog, no matter what metric you use.
Every week nets a few more readers than the last.
Strangers get sucked in from search engines and send me excited email about the wonderful world of weblogs. Keeping this weblog is incredibly rewarding in so many ways, and it's all come from going about my business and just being myself. Sure, it's nice to get noticed, but there's no need to try and shout over the other 500 webloggers out there. It's a big enough room we're in that we can just converse normally. All that shouting will just scare away those folks poking their head in to see what all the noise is about.
