i can type really long posts with my iphone because i have trained my fingers to move quickly and accurately on the small screen. this is achieved by taking many hours of practice and playing games like tap tap revolution that increase dexterity in the fingers. i also make full use of the iphone's auto correct that fixes most of my spelling errors and typos while taking into account the basic context of the word and words around it. the iphone keyboard also has many shortcuts that i use such as the "." shortcut, the "." shortcut is done by double tapping the space bar. the shortcut will create a period with a space after it, for convenient sentence punctuation. the iphone touch screen will also let me copy and paste text to avoid having to quote long paragraphs of information. in fact, i'm typing this whole post on a laptop!
