Double standards in blog reading

[This sounds a bit harsh, but I'm in a snippy mood after two events in a row with blogger friends.]

I've been slightly annoyed by the attitude of friends who expect me to know about every post they blog about. When they discover I'm unaware of some news that happened a while back (e.g. Friend A breaking up with Friend B), they express surprise that I don't know about it. That makes me feel bad, despite me having to read 500 other feeds, many of which are more informative and regularly updated (which is why I prefer reading them instead).

But later on when I mention something that I blogged about (e.g. me being really ill recently, or playing in a jazz band), I can tell they haven't read my blog either, because they respond like they've heard the news for the first time. And I have to tell them my story from scratch, which more or less confirms it.

So far I've kept quiet at such events because it really isn't worth bickering about, but I'm going to post it here just for the record. One day, if I get another comment like "Oh, you didn't read my post last month on how I clipped my toenails?", I might just shove this post up their face. It makes me feel like a 2nd-class netizen, because I'm expected to know everything about them, yet they don't feel obliged to know about me. This may be OK if they're A-list blogebrities who are worshipped by millions - but we're all far from that. A little humility and mutual respect would be nice, especially if we've been friends and equals for years, even decades.

Basically, don't expect other people to read your personal blog fastidiously, and openly make comments about their ignorance, yet fail to reciprocate yourself. It's a kind of double standard which puts me off.
