Originally, I planned on going to Vienna for YAPC::Europe. Then plans changed, my budget was cut and decided not to go... Now, for some less than obvious reason, I'm again planning on going. As before, I'm submitting a talk. The only problem is that I haven't written a single line. I'm still working on my angle and on my timeslot estimation.
Good to hear that you're (again) planning to come to Vienna! If you want to get some feedback on talks you're thinking to do, you can post your ideas to the conference wiki.
And if you submit your talk before 31th March, you can win a book!
