Sometimes when I leave comments on people sites, I will mention a post of my own that is closely related. I will usually even provide the link. Generally I only do this when the topic is actually very related like we have converted the same type of model or the poster is planning on doing something like something I have already posted.
A couple of examples come to mind. Once someone was showing their homebuilt drop pods and calling them ghetto. They were actually pretty good so I provided a link to my really ghetto drop pods. Or more recently, someone was discussing converting a lizardman blood bowl team so I provided inka to a well converted one shown on warseer and my easy one from this blog.
Am I hijacking other peoples comments to get page views or am I providing the community with valuable information. I have yet to have any of the comments deleted and most of the time I get a return comment on the original post about how my post relates.
I do not do this often maybe 1 in 20 comments I leave but I am still wondering if it is ok.
