General   (General discussion, talk about anything.)

Their name is a palindrome.
The group's name is an acronym.
Possibly, the group's name could be stated as an acronym due to the fact that the group's name is often typed as 'ABBA' and is always pronounced ABBA.
The group's name as in reference to the logo was an acronym.
I have used past tense as this was at the beginning of the group's career. The design of the ABBA logo was changed during the group's career, possibly around 1976, and the first 'B' was turned around. Technically speaking, the first 'B' was no longer the second letter of the alphabet but a mirror reflection of that letter and therefore could not and cannot be regarded as the letter 'B'. Thus, the logo, with the mirror reflection 'B' cannot be regarded as an acronym.
Personally speaking, the logo change was only a small change but certainly a great artistic change of design. A wonderful marketing design and strategy as it is powerful and iconic. The truly amazing part of the logo design with its mirror reflection 'B' is that many people, myself included, instantly read it as ABBA. Additionally, many people possibly do not consciously notice the mirror reflection 'B'.

"I am quite surprised actually, that no one has posted a nasty comment on here about ABBA, even Tonker hasn't said anything negative about it"

TTS, Tonker may possibly be an ABBA fan. Send an 'S.O.S.' or give him a 'Ring Ring' to 'Gimme! Gimme! Gimme!' and the rest of us an answer.
