And just the fact that somebody else takes a look at your project -- and I'm sure it's true of other things, too, but it's definitely true in code -- is that somebody else takes an interest in your code, looks at it enough to actually give you feedback and give you ideas.
Nii et pelgalt fakt, et keegi teine tunneb huvi su projekti vastu - ilmselt on see nii ka teiste asjadega, aga kindlasti on see nii  programmeerimisel, et kui kellelegi teisele pakub su programm nii palju huvi et ta süveneb sellesse,  annab tagasisidet ja uusi ideid.
