I have for some time told people that one way that my blog was different was because I was focused on offering a high signal-to-noise ratio. I told them that they could subscribe to my blog safely, as I'd not inundate them with anything but the highest quality posts.
At first, this meant that I'd not post unless I had something significant to add to the topic. No simple pointers to interesting ideas, no simple rephrasing, or simple agreement -- I had to add value.
For some time I think I succeeded -- I received a lot of praise for my posts on social networking, on internet security, on FOAF, on the Dunbar number, and on my tool EditThisPagePHP. However, I've found that for each post my standards were growing higher. My most recent posts took significantly more time to write, and I believe were much more like articles then they are like the typical blog post.
I haven't posted now for a couple of months, and I realized this week that part of the problem is that I've become intimidated by my own standard. For every new post to meet the quality of some of my best posts is too difficult.
So I'm lowering my standards somewhat -- I will be posting some more small, pithy topics, rather then my longer rants. However, I do hope to continue to offer a good signal-to-noise ratio, and still add value.
