I have just now (ok, probably sometime earlier today) gotten 100,000 pageviews! Of which about 70,000 are just me poking around old posts, either because I'm trying to find inspiration for a new post or because I'm trying to find something specific to link to.
I kid. For the last year or so, I've been able to maintain a reasonably steady pageview count, and the number goes up even if I haven't checked in for a while. So it's not just me and my (extremely small) commentariat.
I've noticed that a few of the longer-running blogs in the geoblogosphere, and those that were especially active when I first started writing, have dropped significantly in frequency or have stopped altogether in the last couple of years. So maybe I have more viewers by attrition.
Many of the geoblog aggregators I'm familiar with include blogs that are relatively inactive. Do you have any favorite websites (or blogs) that list a bunch of environmental/geology blogs that are active? I may need to poke around to add to my bloglist...
