If you use read with the -e option (to enable readline), you can also use the -i option. -e use Readline to obtain the line -i text use TEXT as the initial text for Readline unicorn:~$ read -p 'What is your name? ' -e -i "$LOGNAME" -r name What is your name? greg_ Where _ represents the cursor. The string "greg" is pre-populated from the -i option, and can be backspaced or whatever.
