Here’s another sign of Tumblr’s growth: The blogging network/platform has cracked comScore’s chart of the Top 50 U.S. web properties for the first time.

ComScore’s April 2012 report credits Tumblr with 23.5 million visitors during the month, which is good enough for No. 47 on the list. As you can see on the full chart below, that still leaves it behind sites like Netflix and MySpace (Nos. 41 and 42, respectively), but ahead of retail giant Target.

Google, Microsoft, Yahoo, Facebook and AOL comprise the top five, just as they did in March (and for some time before that, as I recall). Here’s the full Top 50:

The single biggest gainer during April was another popular social site/service: Instagram. ComScore says its unique visitors were up 78 percent between March and April, and it’s now 106th overall.
