first off, this is not about 'base 10', it is about interesting patterns found in series of digits, similar (but different) interesting patterns can be found in series of digits in other bases.
Secondly, if every time a mathematically oriented person stumbles upon something interesting instead of figuring out why they would respond like you just did mathematics would grind to a halt really quickly. After all, that's how math started - that curiosity about patterns - and mathematicians really can't help it but they have to figure out what causes this. There may be a trivial answer, or something profound may be found out, who is to know in advance what will come of it.
To everybody else the circumference of a circle may as well be three times its diameter.
