I actually reg'ed a number of triple repeating LLL.in when they first became available 10, 12, 14 years ago - whenever it was. Also had a number of very, very premium top keyword .in. The best names you can think of. After a year I let them all drop. There just wasn't any interest for them back then. That's why I was able to get them... nobody else wanted 'em.
Back then not too many registrars handled .in. Don't remember what registrar I had them with but I do remember they were outside the USA. Certainly not a big deal but... Seems like annual fee was at least $30 per. Expensive when you could get .coms at GD for a dollar with a coupon code which were always available. At the time everybody said it had to be .com, one-word, generic, radio test, type-ins, blah, blah, blah. Because of the annual price, lack of interest, and what everyone else said, I let them all go after a year. Actually it was my own stupidity in not following my own thoughts. I knew one day .in would get online.
Of course, I would have been paying annual renewal fees all this time but... yeah, I regret dropping 'em.
