The master raises his finger for a purpose, it's a tool he has to accomplish something. I'm assuming those who put tags in their titles have a purpose for doing so. Maybe Super Search doesn't fulfil their needs. I'm not privy to their reasons.
The boy raised his finger in mere immitation, without purpose. So... the master chops it off. The boy goes "What the ****! Why'd you chop off my finger?" The master raises his own finger just like he always does and the boy is enlightened, that's the purpose of the master's finger, enlightenment.
Does putting your name/tag/whatever in the Title serve a purpose? If it does I'm fine with it, if it doesn't it gets on my nerves. Especially funky dingbats. I would dislike going to Newest Nodes and seeing some funky high-bit/unicode trash in every title. Like when boy raised his finger.
After reading the many thoughtfull replies to this thread, I don't think anybody was using the 'ego-tattoo' for the only decent reason I could come up with for using one...
I noticed mostly saintish types using it, knew that a lot of them wrote a lot of books and such, and figured it was a good way to track the whole conversation between them and whomever so they could find them later and use them as inspiration for the next book.
I just figured that you could search for your own articles, or somebody elses, or for title, but not for the articles that were responses to things you had written.
So, put your name in the title (for it's uniqueness, not ego) and you can search on that.
