Different players have different styles of writing and of including detail.
Nothing is necessarily more wrong than right, as far as style, format, point of view, etc.
What matters is whether it's something a GM can act on.
Things which GMs cannot act on:
-> Missing details. It is useless to note "I talked to Raymond." without saying why, what motivated your character to do so, informing me whether Raymond knows how to reach you back or whether you'll try again, whether you have other avenues you'll pursue to reach whatever your character's goal is.
-> RP-less giveaways. I won't act on a note which simply says "Can I have a ... !?" when you aren't lifting a finger to act ICly to pursue . Roleplay it and let us know how you roleplayed it.
-> Unrealistic expectations. We don't have a lot of resources to build/invent/create people/places/things which don't exist, just because your player describes an elaborate plot idea and sends their PC off to set it in motion. If it's awesome and can potentially involve other players, it might fire us up and you'll see IC results after we spend some effort setting things up. If it's a thing which is only going to do anything for one person's RP, we're not likely to put much effort into it, depending on the amount of preparation needed.
-> Usually, diaries. Your @notes aren't your character's memory, you have other IC tools for recording things for the character to remember. Goal-less journals of day-to-day happenings MIGHT wind up including the occasional bit of plot fodder for GMs to pick up on, what happens more often is that a journal winds up including a lot of "I did this" and not a lot of "I want/plan/fear this". Also remember, @notes are OOC and are not your character's memory, so, if your character wants to journal or remember stuff, there are IC ways to do this.
So beyond that, just try to think about what you can @note which GMs CAN react to. It has to be ICly plausible and based on actual RP which you either have done or are planning to do, purusing your character's goal. Notes aren't a shortcut around RP, they're a way to let GMs know what you now need or will soon need, to get/keep your RP flowing. What do you know that GMs might not know? As stated above, there is a LOT we don't know. Even if we see some of your RP, there may be dots we can't connect. And we definitely do not see every bit of every PC's RP.
