Well done for getting a site up, and I'm sure the rough edges will get sanded off over coming weeks.

A suggestion:

I'd say the teaser text should be a bit longer on the listing pages, also as it's an automated extract it's too short to deliver added meaning to the headline.

EG on this story it reads: "We are back with a brand-new edition of WP Tavern. Technically, we have a spiffy […] "

I'm not sure that text delivers much added meaning. This text works more as a design space filler in the block than as an information supplier. If it was Lorem Ipsem in a pattern library someone might say "that looks nice", but it's not a useful summary, or any kind of teaser, and as it's an truncation of the body copy it's not supplying much added value to the headline in terms of meaning.

So it either needs a longer truncation word count, or preferably to use a manually typed subhead/summary which delivers better contextual info. Also, the googles love contextual summaries.

For example an alternative (on this story):
"Find out how we used Full Site Editing to redevelop the site. Our year long project, what we learned, and what's next ..."

Might be a bit more useful teaser strategy for you and readers.
