Occasionally, if the person posts something interesting, I like to see what else they have come up with.
I do click on most signatures to see what people do and / or love. Because thre's not much point in advertising a site that you hate
I don't usually, but I may if it's interesting to me on a professional level. E.g. I'm not going to click on your "Cats Roxor" link, but I might click on a "SEO Secrets Revealed!" link.
i do click on sigs...but only on the sigs that seems very interesting like I WILL KILL YOU IF YOU DONT CLICK ME! or FREE 100 PR8 ONE WAY LINK hehehe
I noticed on one of my blogs that i receive a few visitors from DP so...people do click sigs for sure!
All the time. There are some very talented webmasters with some very useful and interesting sites here.
On one forum I do from time to time, but on most forums (including this one) I don't... I see it as a big spam problem! sigs I see "$9999999.." "9.99" "save money" "earn money" "BEST..." "CLICK HERE" "EASY WAY TO..." or things like visit my 50 sites so I can earn ad revenue. Even on this page "$10 Gadgets and Gifts" "Free 50 domain names" "Make money on any traffic."
