Logo wise:
The fattness of the font used for the TARDIS portion means that the "A" and "R" actually look quite similar.
As the "t" of data core is covering a portion of the "A" it makes it even harder to actually tell what the word says.
If you know what it's meant to say it's alright, but I try to look at these things and imagine not knowing what it's meant to say.
So to me, it could say "trrdis" or "taadis".
The "date core" portion is fine if a bit 90s gaming magazine retro.
Name wise:
I have no issue with the name, only the capitalisation of TARDIS, which can be left to another discussion, as long as it is understood that moving forward with the name/logo is not approval to change the capitalisation on the MediaWiki pagetitle or elsewhere on the wiki.
