Hehe, blog is mostly for fun but it kinda helps you to be consistent. People can see how you're doing at the poker tables and you will be more motivated to show some positive results.
It helps one a lot to deal with some general issues, at the beginning I posted my BR and the results of every session with bad beats every time. Several people (Waiboy, erm... some other FL dudes) told in my blog to not be result-oriented and ignore the money. I even did a week-without-looking BR challenge. So having a blog in our great community is definitely +EV.
I use the standard PokerStrategy 500 BB BRM, but with some flexibility. If I have recently had a huge downswing I might apply a bit stricter BRM to feel more confident. And if I have like 490 BB I might want to take shots to the higher limit.
$0.1/$0.2 FL FR and below that is damn easy I believe. It gets a bit more difficult at FL FR $0.25/$0.50, this is where I had my first big downswing. I'd recommend to switch to SH at $0.25/$.50 after mastering the FR, here it can also get tricky as SH is much tougher for a beginner.
I'm breakeven at $0.5/$1 SH (0.09 BB/100 for 75k hands) and losing player at $1/$2 SH (-0.47 BB/100 for 40k hands) but due to rakeback and bonuses I've made it to $2/$4. I feel confident about my play and don't need to play $1/$2 until I get in green there or whatever.
And 1 fish at a table is not enough at $2/$4. It's much fishier than you think, tables with 3 fishes are pretty common
Depends on the daytime, ofcourse.
You could take shots at $0.25/$0.50 if you have the necessary BR. If you play 4 tables, play 2 tables of higher limit and two tables of previous limit etc. If you succeed, then play only the higher limit. Bigger BR gives you more confidence. If you feel that you're not ready to play $0.25/$0.5, grind the lower limit.
I'm happy that you chose FL HE, it's very fun and challenging game
Few things for you to do:
post lots of sample hands
watch lots of FL videos
read and study FL articles, especially the one about standard lines in heads-up pots
go to FL coachings and spam Cornholio and TerrorBlade with questions
