simplysage on "Lot of trouble editing and writing posts from iPad"

I have great difficulty posting and editing from my ipad. I used to be able to do this with ease but cannot anymore. I have iPad2 and have done all the upgrading with software. Last summer when I got the iPad it worked so well and suddenly didn't and now it's even worse. I love using all the other features that work well with iPad but writing and editing are frustrating.
Thanks for your help!
