That's my reasoning behind deleting tweets as well. They just aren't worth preserving. I only tweet about the things I'm passionate about, which are human rights, privacy and politics so I can and do tweet impulsively to vent from time to time. I almost always regret those tweets and I don't want them be on my timeline permanently.
Data mining is a concern, though not a big one because I'm pretty sure twitter keeps my deleted tweets anyway. If I don't want to say something I don't want to be found on the internet, I just don't say it.
I don't tweet a lot, so I've been deleting them manually. Which isn't a big hassle for me. I wanted to use scripts to automate the process but they all require API tokens and twitter doesn't let you have them without giving them your phone number, so I decided not to use them. I try to keep my account as anonymous as possible. If I had been tweeting a lot more, I would've definitely used them but currently they're not for me. Thanks for sharing it though. I'll bookmark it just in case I need it in the future.
I'm fortunate to still have an API token from before they required that :-) Can't make any new ones though. But for the occasional script it can be useful :-)
