"But, it's hard to understand under the circumstances how somebody could, in such a devastating situation, sit at their computer or phone and type," she said. "It's not so much that she used Twitter to reach out or that she was doing a very ordinary activity at such an extraordinary time."
Ross, who tweeted under the moniker "Military_mom," was a prominent mommy blogger on the site Momdot.com. Her friends there had already begun organizing a central place for cards and donations to be sent just minutes after she sent the first tweet announcing the death.
The furor over Ross' tweets has been felt even by those who were critical of her.
McGraw told ABCNews.com that she is receiving threats on her Twitter account by other bloggers who are saying she should be "beat up" for questioning Ross' story.
"The first thing I thought when I saw the tweet was that it was very sad," said McGraw. "But then I thought, 'Who would tweet that her son just drowned?' I couldn't believe it."
"I looked at news stations and couldn't find anything and I hoped it wasn't just another scam," she said. "I asked for verification, and boy did that get me in trouble."
McGraw said that as a former paramedic who has three children of her own, she found it shocking that a mother who had just lost a child could be composed enough to tweet about the incident.
"I've seen people react [to a death], but they're screaming their heads off, crying and they don't know what to do," she said. "They're not on Twitter. I've never seen that before and I was just shocked."
"I think she was very entrenched in Twitter," said McGraw. "And I think maybe her whole life seemed to revolve around social media and now this is a great lesson for all of us."
Ross sent a tweet to McGraw Tuesday morning asking where her heart is.
Trisha Haas, another mom blogger who founded the site Momdot.com where Ross was an administrator and worked on the public relations team, said that it was not unusual for Ross to want her online community of friends to know what was going on.
"She twitters a lot and was very good close friends with people in the [blogging] community," said Haas, who also knows Ross personally offline.
Asked if she thought it was shocking that Ross tweeted the news of her son's death, Haas said, "Absolutely not."
"It's an excellent way to disseminate information," she said.
Haas said that while Ross could have called 200 of her friends, tweeting the news was "much easier" to reach out to all of her friends simultaneously, who then "immediately set in place a support system in one moment."
"As quickly as we can get the information out to support someone is as quick as there's criticism," said Haas, of some of the negative attention Ross' case has been receiving from people like McGraw. "It's very unfortunate that's the reaction."
Colleen Padilla, another mom blogger, said that she too would consider reaching out to the online community in a time of need.
"In the defense of her tweeting during a tragedy, that is her community," said Padilla. "I think today, the Internet is a place where mom's are seeking support, advice and answers."
Ross, who is now mourning the death of her son with her husband Steven, who is in the air force and was scheduled to deploy to Iraq, said that she and her family want to be left alone, and want their son to be remembered as a "powerful little boy."
"He was full of life and commanded attention in a room when he entered it," she said.
