I thought it might make sense to point out some things about agent blogs.
1) All agents, including blogging agents, are fallible.
2) Some agents are bad agents, including a few that blog.
3) Unless the blogging agent indicates otherwise, assume that their comment only applies to them personally, and not for the industry as a whole.
4) Even if the agent does say that everyone in the industry feels the same way, don't necessarily believe it.
Just like any profession, a few bad apples can damage the reputation of the entire field, and so it seems that a few bad agents and their bad blogs have injured some writers' opinions of agents as a whole. I can only ask that you try to keep the same perspective I do when I read queries. I get a few queries every day from people who clearly spent no time researching either me or the industry. I also am the subject of abuse from aspiring writers all the time because I've reached the personal and subjective decision that I don't want to represent their work. However, I don't let the bad spoil my view of the good. I still read and evaluate every query that is sent to me, and I requested six partials last week, my most this year.
