So you are planning to wait to download Tweetie until it becomes free? To save $2.99?
To be honest I don't see what is wrong with saving $2.99. In fact I think it would be silly to go spend $2.99 on Tweetie when you know it is going to be free soon.
The developer probably doesn't need $2.99 from you but I don't mind giving somebody a small amount for a good piece for software.
I upvoted you because you shouldn't get downvotes just because you someone disagrees with a comment. Rather downvotes should only be used if a comment is irrelevant or trollish.
I downvoted you because meta-discussion of when and how downvotes should be used is irrelevant and boring.
