Two hundred posts

The petrophysics cheasheet was one of our most popular posts

My post on Tuesday was the two hundredth post on our blog, which we started 19 months ago in November 2010. Though we began with about 15 posts per month, we have settled down to a rate of 7 or 8 posts per month, which feels sustainable. At this rate, it will be at least a year before we hit 300.

We hit 100 posts on 21 June last year, after only 222 days. In the 358 days since then we've had about 41 700 visits from 24 500 people in 152 countries. The most popular content is a little hard to gauge because of the way we run every post over the home page for a couple of weeks, but from the most recent 100 posts, the favourites are (in descending pageview order):

• G is for Gather (6 comments)
• Petrophysics cheatsheet (5)
• Why petrophysics is hard (5)
• I is for Integrated trace (7)
• Are you a poet or a mathematician? (13)
• Pseudogeophysics (8)
• Wherefore art thou, Expert? (12)
• Geophysical stamps 3: Geophone (10)
• The Agile toolbox (11)
• Stop waiting for permission to knock someone's socks off (10)

Someone asked recently how long our posts take to write. It varies quite a bit, especially if there are drawings or other graphics, but I think the average is about 4 hours, perhaps a little more. Posts follow an idea–draft–hack–review–publish process, and this might be months long: we currently have 52 draft posts in the pipeline! Some may never make it out...

We'd love to have some other voices on the site, so if you feel strongly about something in this field, or would like the right to reply to one of our opinion pieces, please get in touch. Or start a blog!
