The noob who hasn't even read all the 19 pages of this thread (only pages 1-8 and 17-19, but I am working on it, promise!), and has only used one single TPA flavour ever, should probably stay out of this thread, and especially not go all meta.
That said, I've never been good at "should":s, so...
A few things I quickly noticed when I started reading this subforum:
1. The person named Linda who is TPA seems to have done quite a lot for the vaping community, and in a very charming and personable way.
1.a. This brings with it a certain sense of ownership, responsibility, protectiveness on part of many here.
1.b. This enthusiasm is seen by others, rightly or wrongly, as "fanboy"ism, and hence a bit irritating.
2. From what I can tell, TPA/TFA has its roots in molecular fragrances and somewhat instrumental view of taste and flavour.
2.a. This is a style of thinking and doing that doesn't suit everyone.
2.b. People looking for the "simple, solid and forgiving" will most likely be disappointed in many of TPA/TFA's offerings
3. The conflicts or near conflicts ("bashing") occurr when people with a strong feeling for TPA/TFA encounter someone who wants simple natural flavours, and hence voice their opinion of TPA/TFA products as "chemical" or "perfume-y". The latter think they are only stating a fact about their own opinion and perception, the former reads into it all manner of slurs.
4. Further complicating this tension is the fact that many, many people here post rather tersely. Especially when a noob who hasn't found the enter or shift keys, spellcheck or hir grammar asks for opinions, both protectors and detractors tend to become rather short, blunt and heavy on the adjectives:
So you get Respected Old-Timer A boiling down a few years of thoughts into
Look at TPA, they have absolutely everything and Linda is very nice"
Whereupon Respected Old-Timer B thinks that's a bit unhelpful, and opines:
TPA can be tricky, I got the most gawdawful chemical aftertaste when I tried her Fluffy Unicornmeat, just a warning
What gets left out of this exchange is that the mixing styles of ROTA and ROTB are totally different. ROTA probably wants to tinker with different shades of one flavour and don't mind mixing with things that comes with a ppm recommendation. ROTB wants not have to use all hir free time on diluting dilutions of molecules with weird names and sniffing malodorous ingredients with a view to combining them in a way that creates something new and delicious.
And both remember being newbies, and tell the newbies what they wish someone had told them.
