Stewart Sexton, he of the excellent Stewchat blog, has recently posted about the tardiness of some of his linked bloggers to posting. After reading it, I looked at my list of linked blogs and, guess what, ten of them haven't posted for over a month! To be honest, I reckon that only 30% of my links could be considered as regular posters. Not everybody has the time or the inclination to do so, but as Stewart points out, there does seem to be a reduction in the frequency of posting out there.
Other 'social media' strands have a lot to do with it. Facebook groups allow illustrated (not word-restricted) posts which are targeted at a defined audience. Twitter is deliberately brief and quick. Blogging does require some commitment to the cause. There may also be a case that many bloggers are coming to the point where they are running out of things to say, and if they are using the platform as a way of reporting along the 'been there, seen that' lines, then it is easier to send out that information in other ways.
I have been tempted to reduce my blogging frequency, even considered stopping altogether (I did kill off the original ND and B). However, a blog is a lot more than a collection of my thoughts and records. It is a creative outlet. Sometimes - on the rare occasion - it can be a service to others, making them aware of places and species. I have been corrected on my identification, mainly regarding invertebrates. I have met up with fellow bloggers purely through our Blogger contact. I have a number of 'virtual' friends who I have never met, but enjoy (ir)regular communication with, either through the comments box or the forging of private e-mail correspondence. It seems to me to be the most personal of the 'social media' platforms, as you need to make the effort to visit a site - a post won't pop up on your phone whether you like it or not.
So I would echo Stewart's call for bloggers out there to keep on blogging and for those that have fallen by the wayside to get moving again. I enjoy trawling through them. They educate me and they entertain me. Your audience awaits!
