Blogging can be a lot of work, but I totally enjoy it! I started because initially I wanted to get a place where I can collect all the information that I have come across over the years. Sort of a central archive area for reference. Having a really bad memory problem, I constantly end up rereading things and this was a way to keep the stuff that's important to me in one central, easy accesible location.
I have had a "WIP"section on my web site for the longest time, because clients really enjoy seeing the progress of a painting. But then a funny thing happened. More and more artists started to ask me how I did this or that or if I would be willing to teach them. I was surprised by the response, but find it a great way to share what I have learned. It also stops me from taking shortcuts, now I have an audience and pressure is on to push myself even further. I see a great benefit in this alone!
My hits on my blog have sky rocketed and it has a lot to do with people subscribing to the RSS feed and linking. This helps to create a web presence and increase the chances of people actually looking at your web site.
My website's function is like that of a gallery. It represents the collection of my work. There is a link from there to my Blog for those who enjoy reading. I try to add other things such as book reviews, cool links anything that might make the experience of reading enjoyable.
I am still waiting to be discovered! LOL
