Since i have subscribed on SF and been active on it i have read tons of interesting questions with very interesting answers.
Those questions, and answers (i didn't ask myself), make me positively review and improve some things i have setup in my own infrastructure (network design optimization, script improvement etc...).
Each time i read a question which i could be interested in, i have to put it in my browser favorites and come back regulary to check if it has been answered.
I think it could be interesting to add a feature that would enable to "follow" a question and be notified when there is activity on this question, e.g by using the same pin notification used for comments.
Those followed questions would appear in the user profile activity so that they could be accessed very easily from anywhere (browser favorites independent).
I am interested in your opinion about this.
