If I happened across a blog written by a moron, that contained a personal attack on me, I’d probably respond to it something like this.
I’d suggest that they didn’t ramble on and on, like somebody just back from a binge drinking session and lacking the brains to go to bed and sleep it off instead of scrawling on their blog page. I’d also suggest that they read more carefully what they are ranting about before going off half cocked, like a spoilt child that’s just been told they can’t have a sweetie.
Finally, I’d tell them that, if they want to keep banging on about something written months ago, all of the above applies and that they shouldn’t think themselves so important that everything that was written all those months ago, was only about them.
Oh, and if I happened to try to find out a bit more about the writer of the blog and took a look at their profile, I’d be very suspicious if I found that it actually contained absolutely nothing about them, or anything else come to that. I’d also have to wonder what they had to hide and ask how they expect to be taken seriously, when they hide themselves from their readership.
Of course I’d only respond like this if I happened to come across such a blog entry.
Likewise, if the site was just a regurgitation (vomit for short) of other people’s stuff, this would clearly show that the owner had a lack of original thought, so it wouldn’t be worth reading in the first place, so I’d probably never bother reading it and wouldn’t have to respond like this after all.
