Just had an awesome feeling to find my very first Blogger blog which was created back almost 16 years. I had no idea that it existed, as it was created using some username which I had forgotten long back.
Found this while trying to go back to legacy view of Blogger and instead stumbled on claim Legacy Blogger link (https://www.blogger.com/legacy-claim.do). Try it out, if you happen to be also like me, who had jumped to Blogger when Google had acquired and completely forgotten about it.
