I do not like
In case you are wondering, this is what people write to indicate they are doing, except not really. Much like "LOL" really means "silently smiled to myself," *grins* theoretically means I am grinning right now, but what it really means is "I am happy and/or pleased with myself, and the twitterfication of the English language has led me to abbreviate that sentiment with *grins.*"
But the bigger reason that I dislike *dies* and *grins* is that they are too dramatic.
Not to pull a Daria here, but really, isn't *shrugs* *mehs* *rolls eyes* *stares blankly and turns back to email* a lot more accurate than *dies*?
To end with the ultimate internet send off: Just sayin.
