Take it easy.. don't bother about it too much which you are taking it well and doing fine.
In a forum, there are basically these 4 type of people
Talk Sense, Talk Nonsense
1. Can afford A C
2. Cannot afford B D
A. Talk sense and are wise.... what they say are valuable
and they can afford it.
B. Even though they cannot afford, they still talk sense and are wise.
C. They are rich but they spew alot of nonsense
D. Cannot afford and talk alot of nonsense
Basically, we read any post we like and distill our own judgement, nobody knows for certain whether they are right or wrong. I find people who call others sour grapes are the truely sour grapes themselves.
