What about the verb "put"? Today I put my keys on the table. Yesterday I ____ [put] them there. I have always put them there. You don't say "putted".
The following verbs work this way. Hit. Hurt. Set. Split. Let. Bet. Cut. Burst. Why would the word "text" not work that way? The only reason I can think of is because too many people started saying "texted" and the result has been that others are hearing it that way... so they say it, too... because in their world it sounds right. Therefore, it is becoming common, even though, by my grammar background, "text" should be the proper past tense of the verb. If your mom says "I seen" or "they've went" the whole time you're growing up, those sound right to you. But they are wrong. And we do have rules in grammar for a reason.... so we can understand one another's thoughts and meanings. If we don't all follow the same rules, it causes confusion. Language must have rules. But language is fluid and changes over time. That's why English is such a mess in the first place... because it was influenced by so many different groups of people over a long period of time. Now here we are.... with a new word. And we can't agree on what to do with it. No doubt, however the media handles it, that is how everyone will eventually use it. Comfortable or not. Or it will end up being like other words that came to have options. Yesterday I [hanged or hung] the flowers on the balcony. There was probably a huge debate over that one once upon a time.
