DailyMile is where it's at. I don't know why people bothered with Strands.
Yes, some famous runners were on there but they rarely posted workouts. Strands had a horrible user interface. Dailymile is easy to understand, looks polished and it just makes sense from day one. It's also highly social. You actually get to know other runners (instead of just cutting people down on letsrun), share training and encourage one another.
That's why DM has been successful and keeps adding users. I know people are going to poo poo DM as being for "hobby joggers" but I don't care. It's a great tool and there are apps that you can use to post workouts to it from your phone as well.
