Nice to see internet companies chasing ideas besides just advertising. People don’t mind paying for some things – for example, Flickr is good value in the pro mode and I’ll certainly re-up when the time comes as I really like the additional sets for organization (and don’t have time to abuse the bigger upload limits either).
Also of note – I created a simple Tumblr page to extract inline posts and comments from this blog, and had a little trouble getting my feeds in. The Tumblr help desk was very quick to the punch. While the problem turned out to be a temporary Feedburner issue for me, it’s nice to see a “free service” actually give you service, and I applaud Tumblr’s timely support.
