A unwanted post placed on a blog that is used for soliciting purposes. Like spam, spim, spat, and spobile, these messages contain links to websites featuring the usual array of forcibly advertised online services, such as pornography, credit repair, and prescription drug sales. The messages may be made to appear as a comment from an interested reader, stating that the posted link is to a webpage relevant to the current discussion, or an invitation to view the spolgger's own personal blog.
Wow, I totally agree with you. <Click here> to check out my blog.
n., combination form of spam + blog: 1) blogging solely for profit v. personal expression, communication, information (et al) purposes; 2) a blog which exists to pimp products, services, websites, etc. via extensive use of ads and/or links.
A good friend of mine used to have a slamming blog, but she's become just another sell-out, now that it's nothing more than a splog. I doubt she'll ever get rich using all those pay-per-click ads plastered everywhere on it.
