they like that if they want to see a grow log on a sweet seeds strain they go to the sweet seeds sub forum , or if they want to see one on a dutch passion strain they go to the DP sub forum , then they dont have to look through 39237264 different grow logs to find the specific log they are looking for
That example seems like the exception. To illustrate:
Someone might grow Sweet Seeds but put their journal in the Hydro forum. Or, they might use organic nutes but put their journal in the LED section (maybe even the New LED grower's section because they're new to LEDs. Or, maybe the New Grower's forum because they're not just new to LEDs... but new to growing.).
So, while you have a good point that it's easier to find Sweet Seeds grow journals in the Dutch Passion forum -- there's no guarantee that's where they'll be. Now we're back to looking for Sweet Seeds grow journals in a few different places. A person might be lucky and find some. But, wouldn't you like to see all of them (and quickly zero in on those that are indoor, organic, LED?).
I don't know how you could answer in the negative since you just validated that convenience is an important element of this topic.
