But sometimes it is because some posters know info about the op from other posts that targeted advice can be offered and badly targeted advice picked up. The only way to avoid that is to insist that all new posters put thier meds, diet etc in thier signature, which I dont see on my phone. Its not that I disagree with your idea, just that it relies on the op, often a confused newbie (like me jus a few weeks ago) does not give out al the info needed.
It is even worce then this, as someone may have thought they were Type2 at the time of the post, but later discovered they are LADA, so someone reading the thread in a few years time, does not know it was posted by someone assumed to be Type2. (Google tends to find old threads.)
