When I first noticed SBI, I was confusing it with SPI, which I started 'collecting' a couple of months back. But then one recent Pun-day the punster in me awoke and I posted a punny pun about Christmas and won - 8 SBI! So now I am delightfully aware of the difference between SBI and SPI. Alas, awareness does not equate to understanding, so I guess I need to find an SBI-101 post to fully appreciate my good fortune.
Also, wouldn't steemleo be another good tag as SBI is investment related? Cheers!
